moving...

I think I'm going to try to create a group on facebook that can handle the calclueless discussions...
more to come when I figure it out...

Bye Everyone!

Thanks to all those who took the time to answer my questions. You know who you are, Carol, Maria, Tiffany...

And especially Mrs. Carlson. You are certainly the hardest math teacher I've had. But I learned a lot more as a result.

So thanks everyone!

I'll be back

June 3rd.
Apparently I have a "disc bulging disease in my L5-S1". But I'll be okay. I have an appointment with Physical Therapy scheduled already, and will figure out how to deal with it. Thankfully it's not MS or something worse.
I'm looking forward to coming back. =)

Mrs. Carlson

Sooo...how was it??

I was thinking about all of you this morning...wondering at what part of the test you were on during various times...
Did you feel prepared for the FRQs? Did they have anything on there this year that seemed different from the years past? I can't wait to hear from you guys!

Good luck tomorrow morning and I'll be thinking of all of you!

I won't be there tomorrow as I had thought; I'm now awaiting an appointment with Neurology. So I'll be gone at least 2 more weeks. But don't worry about me.
You are prepared, for the most part. Just go over the Formulas & Theorems packet for any last minute items you might want to review.
I wish I could be there for you!
Tell me all about it later, okay?!

-Mrs. Carlson

I hope it helped...

for those of you that showed up, I hope it was helpful. It was nice to be there. Makes it easier for me to go back to work. =) Of course I'll be sad having to leave the new baby, but I'm comfortable in the classroom, if that makes any sense.
Please continue to post questions!

I *still* haven't yet heard back from the doctor. I had called again on my way to the review. Soooo, right now I am assuming that I will be back there on Wednesday. If so, I will be in my room around 7:15ish for support and last minute pep-talks.

A couple of things to do beforehand:
-make sure your calculator has fresh, new batteries. or bring some with you.
-set your calculator to RADIAN mode
-NO scientific calculators allowed; so leave them. you are allowed up to TWO graphing calculators (no QWERTY keypads allowed; so TI-89s are OK).
-breathe. you'll be fine.

Get a good night's rest and eat breakfast. don't load up on sugar. eat something healthy.
See you there!

Mrs. Carlson

Here's what we'll do:

Tomorrow, Monday, at 5pm in my room for 2 hours. I will double check with Mr. Wentz to make sure the time is ok to be on campus. If not, I will let you guys know. I'm sorry it can't be sooner or longer. I'll actually have to have Brennan (the littlest one) with me (can't get around this).
I can't come on Tuesday because my son has a baseball game Tuesday.

I will *hopefully* also know sometime tomorrow what day I will be returning. Again, I will let you all know.

So, please spread the word about tomorrow.
Thanks!

#22 and 23 from MC Set #2

For #22, how does the answer come out to be e? I keep 2+e, which is the answer for choice C. Does anyone know how to do this?

For #23, I don't understand this problem either. Any help would be greatly appreciated..

Thanks.

#14 from MC Set#2

I keep getting 120 lbs. Is it supposed to be 120 lbs or 60 lbs. Does anyone know how to solve it so that the answer is D (60 lbs.)? Thanks.

How about...

if our campus can't accommodate us after 6, how about at the library? In one of their conference rooms? Does it need to be reserved? Can that be done ahead of time? Does anyone know?

Q&A Session

Hannah emailed me to ask me if there's a possibility of having a Q&A session Monday or Tuesday to clear up questions. What's the time that would work for most of you that would be interested? Monday like at 4pm? Tuesday?
I am set to return Wednesday (story about all that on my blog later) and your exam is in the morning, so those two days would seem to be the best candidates. I'll still need to double-check with my husband to make sure that he can watch the kids, but I'd anticipate that I can be there for about 2 hours.

Please post your suggestions as comments.

MS #2

9. I got 3x^2(x)^(x^2)(lnx)
12. I moved the dy and dx onto opposite sides and ended up with (1/(x^2-x^3+1))^.5
14. The formula I used was the antiderivative of (10/4)x from 10 to 14, which is 110.
15. I don't see how e^(-x) converges, since, as the particle approaches infinity, I got 1, which by nth term would mean it diverges.
20. This is confusing since, by the information given, you can deduct two different answers for radius
22. Since the numerator is an additional equation, maybe the n! crosses out the numerator, but I don't see how the relationship of the function with e.
23. Integrating it, the function looks like sinx-x+(x^3/3) from pi to zero, which does not equal to pi.
29. Looks like the derivative of cos(x+h), but where did the 2 in -sinx come from?
33. When setting the ln function to infinity, I gor pi/1/1/x, which when appraoching infinity, should equal to zero, which would make the answer (a). Did anyone else get that?
36. My answer slightly differed, with 3x^2(x^2+2)^(1/2). Did anyone else get that?
44. The answer makes it so that x(t), not a(t), tells the time when the v(t) is increasing, but why?
Lastly,
45. If n is approaching infinity, then wouldn't the answer be a)0, since (1/n) approaching infinity is zero and sin(0)=0?

Limit of a series

Does anyone know how to do problems like set 1 #43? I don't remember learning anything about finding the limit of an infinite series. Anyone know what to do?

Set #1

Let's get straight to the questions.

5. I'm not able to come to a conclusion from the info given
21. Do you differentiate the unction and if so, what comes next?
23. I got (1/h) [ (-e^(-1)/2+(1/2e)]
28. The functions looks more like a parabola than a sphere- I'm not sure how they arrived at a volume here.
30. I anti-differentiated it to (e^(1+lnx))/(1/x) and then came to 16e-4e=12e.
35. I differentiated [(1/2)y(3^.5/2)y] and got 36(3)^.5
36. I differentiated x^2-kx from 2k to zero and got k^3=54.
37.For f'(g(0)), I got 11, so it already isn't working out for me.
38. Using the arc formula, I came to [(35-4x^2)/(36-4x^2)]^.5, which I should differentiate from three to zero, although the answer seems unlikely.
43. I don't see the connection between the antiderivative of x^2 and the limit above
45. We're not allowed to use calculator, so I'm further perplexed as to what they're trying to find.

Thanks for your help.

#20 from Multiple Choice Set#1 - No calculators

Does anyone know how to explain this? I tried plotting points, but my graph doesn't come out as the same one that they give us.. what am I doing incorrectly?

#20

For part A...
How come the third term is (1/16) when even the solutions say 2!/4(4) ?
For part B...
Where does the (x-5) in the Ratio Test come from?

#4, Error Problems

I'm stuck on 4. I can't find what the general form of the derivative is, and I can't set up the general term of the power series, so I can't continue on with the problem. Also, does anyone how to solve the error problems like 4c. The solutions mentioned the alternating series test, but I don't think we ever learned how to estimate error with alternate series. Anyone know what to do?

Finding IOC

Hi guys! Is anyone here good at finding the IOC? I have difficult time with this subject so can someone please help me? For example: Infinites Series number 4. How would you know that the IOC is -0.6_< x _< 0.6? I am confuse.

Infinite Series Homework Help

Infinite Series is really difficult for me to understand...
Anyways I need help on #2-c and #4-c...
I know for number #4-c you use the Remainder Theorem but can someone help me understand how to use that please.
Thanks

This is for Mrs. Carlson:
When using p-series or harmonic series, do you have to equate it to DCT or LCT or can you just write the similiar equation and the formula?

For instance, woudl 1/n, diverges, harmonic series, be acceptable or do we have to equate the similiar equation to the orignial equation through DCT or LCT?

Onto the HW:

6b. The answer integrated it and as the limit approached infinity, it was heading towards infinity. Why, then does it diverge? It's not using the nth term test, is it?

9b. Since f''(x) is less than zero, does this mean that there is a relative max as x=2?

13c. I don't get the significance of the integral's limits being at x=z and x=0. There doesn't seem to be any difference.

14a. When testing endpoints at x=-1 and x=1, the resuult tends to be the same. So why the function diverges at x=-1 and vice versa at x=1 leaves me puzzled.

15b. a= -3(1/4) and it looks like r=1/4. But the answer would equal to -1 then and that wouldn't make sense.

Infinite Series

Wow, what a confusing chapter

2b. The answer antidifferentiated it and added a "c." When integrating a series, do you always have to add a c? Also, I don't get how they got c to equal to -2, I mwan, I know they put ln(2-1)=0, but I don't understand why they did that.

4a. When you find f'(0) and f''(0)...I got -4xe^(-2x^2), 16xe^(2e^9-2x^2), so when you plug in the zero, f'(0)=0 and f''(o)=0, so apparently, the answer is just f(0) , since the other functions=0. What am I doing wrong?
b How do I know IOC if I don't have an r?
c.The answer put it at lf(x)-g(x)l is less than or greater than (16x^8)/4!. How did they know to stop at the 4th degree?

7a. I don't get how they found the equation to use to for finding the IOC.

9d. The LaGrange formula confuses me because I don't know to which degree I should use. In this case, they use it to the 4th degree.

10b. The LaGrange formula confuses me because I don't know to which degree I should use. Why is it the 4th degree in this case?

If you don't get what I'm asking, could you just show me what ways you used to solve the problem or what I may be doing incorrectly? Thanks.

#4c from HW #21

Can someone explain this question? Thanks.

HW 21

Does anyone know how to do 2c?
Thanks

#18 from HW #19

Does anyone know how to do this problem? I looked at the solutions and they used an integrating factor? Can someone explain this to me? Thank you.

Particle motion

6d. For 5c, the answer was simple- when is x=0? But how do you solve this question?
7 is really confusing for me because they don't explain where ABCD is located. For 7a, how do you know that dy/dy and dx/dt at C is increasing?

Also, which concepts we should review for the quiz, Mrs. Carlson?

quiz on friday

is it only based on this week's hw
or also spring break's?

Need help

This isn't good- I don't get a lot of the hw questions (Are there step by step answers for the sets?). In any case, let me point out a few that I have trouble on.

Set 1
18. I looked for A', which is .5(bh'+hb') and got .5(-20(.5)-15(1/3))
30. The answer is e but e doesn't satisfy the first requirement

Set 2
4. I don't get which formula I should use
15. After cross multiplying, I got y=2x
19 I have no idea how the nswer is a, besides the fact that there is an asymptote at y=10
31. Which formula did you use?
33. You l'hopital, I differentiated it to -8sin4x and -32cos4x and neither solution matches the answer
39. Don't quite get how they shaped the formula.
40. I differentiated it and got zero

Set 3
4. Which formula did you use?
7. Isn't is 3/4
9. I got -1/720

Thanks

HW#19 & #20

Does anyone know where I can find it to download? The Polar/Parametric problems? When I click the link on Edline it doesn't go to the file. Thanks!

#6b from HW #17

I got the speed but I can't find the acceleration vector. I thought to find the acceleration vector you just find the second derivative, or the derivative of dx/dt and dy/dt, but my answer isn't the same. Does anyone know how to find the acceleration vector? Thanks.

Number 10 from Set #3

Can anyone explain how to do this problem? Thanks!

Set 1

How would you do #2 and #29?
Can someone explain please?

Number 30 from Set#2

To find the volume do we find the area of the base and multiply it by 2 because that's the height? Because that's how I was doing it but the answer isn't any of the choices and then the answer key says the answer is D but I keep getting that the value of D is the value of the base. Am I doing something wrong?

Finding growth rate

I was wondering can someone explain to me how you find the growth rate when it gives you the differential equation (which models the growth)? Or do you remember the section that we learned this?

I'm sorta referring to problem #18 in second multiple choice set if you don't understand my question.

Thank you for any help!

MC sets

I was wondering if our homework is all of the sections of the MC packet. It says set 1 online, but does that mean only the first section on differentials?

MC set#1 answers

Hi Mrs. Carlson,
I think that one of the answers on set #1 is wrong. #30's answer says E but I don't think that is correct because the question says that the limit as x approaches 1+ is -inf. and choice E is not correct. I think the answer should be C. I would appreciate it if you could check it out.
Thank you.

MC Set #1

Limits, Differentiation, Applications of Derivatives:

#20: how do figure out the equation of the tangent line?
if g(x)=f^-1(x), then if f'(2)=3/4, would g'(-3)=-4/3?

#22: How do we use the Mean Value Theorem to find c? I know that c'=(f(b)-f(a))/(b-a), but how do you use that to find c?

HW #15: 18c

I know the hw packet is due tomorrow, but I just want to know how you find out that P is a local maximum. I looked at the solutions, but I still don't get it!
Have a great spring break everybody!

Hw #12+

#12
1d. I get how P'(o) =2, but why is t=5?
2a. How did it arrive at y=.5?
4a. What formula was used to find out the limit? Is it the sae used for 2a in #13?
4b.The answer states it occurs when the population is half of the carrying cpacity- how do you know that?

#13
2c. The range is just when f(x) is positive. Is f(x), then, only a function when it's positive? The same thing happens with 5b.

#14
1b. Strangely, when I do it, it's -(2+sinx)sinx-(cosx)^2=0, yet the answers say it's at sinx=.5. What am I missing?
9b. I don't get how they found the x and y intercepts.

Thanks for your help!

Test on Friday

I'm confused over which subjects we're going over- it seems like a mix of past topics. Can you tell us which chapters we should be paying more attention on? Because I'm looking up the topic that's stated on our hw, and the chapter index doesn't give many pages on it...

When they say "justify our answer," I'm stumped because when the hw answers justifies it, it's often in different ways. Is there one, consistent, formula for justifying your answer? Like:

The realtive max is at x=1 because f '(x) changes from postive to negative at tis value
The relative max is at x=1 because f (x) changes from decreasing to increasing at this value

Just making sure.

Hw#12

I can't open it on edline. Can anyone open it?

I goofed.

Okay. So I guess creating a quiz right after having a baby makes for a bad move. Why?! Umm, well, because you were right, #4 (the second FRQ) requires the use of a calculator. That on top of not realizing that Friday was a Double-4th Assembly day, and Mr. Chun not knowing it as well. Soooo...there are two things to tell you.
(1) I will not be counting the quiz that you took on Friday. I will grade it, however, and award some extra-credit points for your efforts/work.
(2) You will be given a NEW Quiz #3 to take. No, unfortunately you don't get a free pass on this. You're going to take it on Tuesday. Personally, I really think it's rather easy (easier that the other one?) so hopefully it won't take you the whole period and you can still work on or check your HW.

Please share this info with anyone else you know in class.
Thanks!

P.S. If there's anyone that still wants to be added onto the list of blog authors, email me and let me know.

Mrs. Carlson

Questiom about #26c

Hi Mrs. Carlson. I was just wondering if you knew what 26c was asking. Did the question get cut off(?) because 26 c only states something but it doesn't ask anything. Thanks!

HW help

#2a) I don't get the process that cound the x-coordinate and point of tangency between f(x) and g(x)

#7c) Since the area between the two functions from x=-2 to x=0 is revolved around the x-axis, why is it that the function is subtracted from the chord when you use washers and not the other way around?

#9b) I'm having difficulty understanding how they differentiated from(e^x-e^(-x)x to [xe+xe^x+e^(-x)-e^x].

#10b) How did you determine that 1/b is the slope of l and why does b=1/n?

#18b) How was it determined that A(w) would equal to we^(-w^2)?

Thanks

yesterday's hw #5

how would u do this question without graphing calculator?

HW#9 Area and Volume 10b

Does anyone know how to do 10b. I don't remember how to do it.
How do you find the area of T if you don't know the base of the triangle.

Area HW #1

A few questions that I've been absolutely stumped on:

#3a. Let R be the region of the graph of y=lnx and x=3 and the x-axis. When finding the region of R, I differentiated y=lnx from x=0 to 3. My answer was 3ln3-3, but it should be 3ln3-2. Did anyone else get this answer?
b and c. I am also confused as to how the volumes were set up.

#4c. Why is it, when you use disks, the endpoints of the differentiable equations are different?

c. I got k=4 when the answer is k=.995. I divided the answer in 6b in half, differentiated the function, and then put k in the place of x. Then I graphed it to see when the differentiated function matched y=one half of 6b. What am I doing wrong?

#7. What do they mean by the chords A(-4,0) and B(0,2)? How do you figure out if it is tangent to y^2=8-x^(3/2)?

Area and Volume 5a/3b

Anyone know how to do any of these problems? On 3b I end up with pi(lnx)^2, and I can't integrate it. Does anyone know how to integrate it without a calculator or is my equation wrong? I have a similar problem on 5a; I can integrate the cos x in my equation but not ln(x^2+1). Scientific calculators are allowed but I don't see how they help. Anyone know what to do?

Unfortunate

It appears that a number of students are merely copying the solutions down for the homework, and not bothering to do the work. This is NOT GOOD, you guys. When I start seeing IDENTICAL work for people, that basically just mimics what's in the solutions, I know you're not getting it.
You need to utilize this blog for questions/help. I saw a lot of that when the AP Calculus Clue was given. You need to do that again.
Either that or post questions and ask me to consider commenting as well.
I am going to be much harsher in grading those homeworks from now on.
Beware!

I need to know...

Have any of your parents expressed concern regarding my maternity leave? I received an email from the principal regarding this and my sub (Mr. Chun). I'd like to know because it concerns me, my class, and well, ME! I'm not upset or anything. Honest. Just curious and concerned to know what the "concerns" from parents have been.
You can read the email on my other blog's post.

Out of Curiosity

Hi Mrs. Carlson,
I was wondering if we still get bonus pts for wearing our shirts on Wednesdays.
just curious (and hopeful).

AP Calc BC Review HW # 4

Hi.

I have trouble with HW #4, number 5c. I kept getting 1.32 instead of 1.52. Can someone please help me?

-Jean R.

HW#2 Riemman Sums

Hi Mrs. Carlson,
The homework is not opening on my computer. I am not sure why but it isn't. I was wondering if you could check it out. Thank You

Hi Calc BCers!

Hey guys...I am here...sort of. Busy trying to get your stuff ready. Nope, no baby yet. =)

I have RE-POSTED ALL of the worksheets so far. Special notations: "$" means scientific calculators allowed and "*" means graphing calculators allowed. Otherwise, NO calculators allowed at all.
Also, I fixed some typos and added in THREE problems each on the Riemann Sums (Tues/Wed HW) and extended the Slope Field/Diff EQs to include Euler's Method and made it 2 days' worth.
Please just go check it out and share with others in the class.
At the end of the problems are the answers, as well.

I will see you guys tomorrow morning (unless something happens in the middle of the night...)!

-Mrs. Carlson

Related Rates

Mrs. Carlson
Are you okay?
If you are, can you post the solutions to the related rates worksheet?

HW #13 - 87 - BC5 c

Hi. I was just wondering for 87 - BC5, I found the equation in terms of x and y but I don't know how to find the interval for T. Does anyone know how to find the interval of T? Thanks.

mrs.carlson-if you have time, could you post the answers to the FRQs, so we can check our answers? or is it on edline already?

Test on Friday

For the test- do we need to know subjects covered in the book but not in our notes? These topics include finding ground speed and direction (#65 in #12 hw) and using the symmetry test for polar functions. I'm having trouble in both areas.

HW#7

On the blue homework sheet that Mrs. Carlson handed to us at the beginning of the year, the problems are #49, 51, 53, 54, 57, 58, 64 wc, (67). On the edline page, however, it says to do #49-63 odd, 64, (67). I was wondering which assignment we are to follow. I was thinking maybe it was supposed to be the assignment from the homework sheet, because Mrs. Carlson said before that all of the assignments on Edline were from last year, so maybe she changed the problems. And also, do we have to do the graphs for number 64? That's a TON of graphs! Thank you!

HW # 6 or 8

Mrs. Carlson
I was wondering if our homework was HW #6 or #8 because someone wrote HW#8 on the board, but shouldn't the next homework be #6?
Thank-You

Question on today's homework

Hi Mrs. Carlson,
I was wondering if we had to do (a) graph for #s 5 & 7, and, if we do, do we have to do it on graph paper?
Thank you

Opener Solution

I'll have it posted on edline for a day only.
Please read the comments.
I'm now VERY tired.
It is waaaayyyy past my bedtime.
See you guys in the morning.

I'm a little worried...

I've only graded a handful of openers from today. I am seeing some scary things on the papers.
Here are some things I need to set straight:

1. Identify the test you use!
2. The Ratio Test only works for series with POSITIVE terms. Otherwise, you must use the Ratio Test for Absolute Convergence, which means you need the absolute value bars over everything.
   
3. You can NEVER get a negative value after using the Ration Test. Why? See #2 above.
4. The Ratio Test is INCONCLUSIVE when the limit = 1.
5. The Alternating Series Test is INCONCLUSIVE if it fails.
6. You do NOT want to compare 1/(ln(k+2)) to 1/k. This does NOT compare well. But you CAN compare it to 1/(k+2).
   
7. When checking the endpoints, simplify before you do anything. It will make it so much easier to figure out.

I don't know...I have to get back to grading those. I am dreading it...I hope they get better.

Solutions to HW #17 FRQ

Mrs. Carlson
Is it possible for you to upload the solutions to the FRQ today, so we can have an additional day to review for the test.
Do we only have to do the three problems or do we have to do the supplemental problems too?

Solutions to HW12?

Are there solutions online for HW12 for LCT and DCT, not "Ch 9 HW#12" for Integral Test and P-series?

hey pplz do we have to do hw # 12 cus we didn't go over it in class and i no we did LCT and DCT a LLLLLOOOONNNNGGGGG time ago but i'm not sure how to do it w/ series... so wat did u pplz do?

HW #11

Hi!

I have trouble with #6 and # 9 on HW #11. Can someone help me?
For #6 are we allow to use p-series test? I try p-series and it converges.
On #9. I use L’Hopital’s Rule and I found out that it also converge. Does anyone know if we can actually use that rule? It wasn’t not the sheet though.

Updated Course Expectations

I've updated it for 2nd semester. If you bring it in signed by Monday, Feb 4th, the first day of second semester, I'll give you 3 extra-credit points. I know it's not much, but I'm not asking for much either. Otherwise, I'll be giving you a copy in class on Monday. They are due no later than the end of the week.
I've also added in a "Dear Mom and Dad" letter. I simply want you guys to take a look at it so that you're aware of what it is and what it looks like. You do not have to bring that signed. Not unless you anticipate on doing something (or not doing something, for that matter) to warrant one.

Have a good 3-day weekend! [I wish I had one...]
See you next week.

HW #8 and #9

For hw #9, I'm thoroughly confused as to how to get the answers to #15 and 16. From the edline answers, it just moves to quickly from one point to the answer.
I'm even more confused with the past hw, #8, with the Remainder Estimation Theorem. Is the rule of thumb simply that the remainder is the same number we get if we used Taylor's Theorem with Remainder? And what exactly is the M of the equation? An explanation on any one problem in hw #8 would be nice. Thanks.

quiz

do we still have quiz on monday?

Question about 8 and 9 for HW #7

Hello. Sorry if this is a "dumb question" but I was just wondering.. since it doesn't say what n equals, do we just use n in our equation and find the (n+1)th derivative and use it to find the LaGrange form of the remainder?

Question about HW #6: QR 9.3

I don't understand what the questions are really asking. I went to the homework solutions to see if it would help, but I'm still confused. If anyone understands the QR 9.3 of HW #6, please reply back. Thank-you!
Much appreciated,
Jennifer Oh

Multiple Choice Questions

College Board keeps those multiple choice questions pretty close to themselves. There are many review books out there with quite good AP-like MC questions. The sample MC tests that I have used with you guys on your Summer Assignment and the AB review were all actually AP-like questions. Some of them (and Mr. Brose can attest to this) are so similar that they might as well be.
I believe the reason for them not releasing them the same way as the FRQ questions is because they reuse some of the questions from year to year. So they don't want it "out" there.

FYI

I know and have heard that some students studied the available FRQ questions that are posted by the College Board. It is OKAY with me. Honest. If there are those of you that are willing to study all of them to help yourself prepare, by all means, do so. To me, that means that you are at least studying.
However, I had considered changing the year as to which I selected the problem for you to do on Day #2 and #3 of our exam. But I didn't. No big deal.
I have a collection of FRQs dating back to 1969. That's almost 40 years' worth of questions to select from. So if YOU feel like studying them all so that you know how to do them all in anticipation of any future Openers or Tests or whatever, again, by all means, please STUDY. =)
So don't be afraid to make mention of this to me. I know that some of you might be feeling guilty or worried about others that have done this, but don't.
Okay?!
Hmm, I guess if you had no clue about this, this could be quite revealing information. Yes, the College Board releases the FRQs.

See you guys tomorrow when we tackle POWER SERIES! Woo-hoo!

Semester 1 Summary

Hey people that study late. I uploaded a little summary I did originally for myself just to have an overview of what we learned. The page numbers and chapter lessons might be a little off because I used a newer edition of our calculus book, but it's pretty much the same.

So here's the download!

AB Clue Problem Set #14

For the suspect problem, I set the two numbers as a & b.  Their sum is 30, so a + b = 30.  The sum of their squares is a minimum so a^2 + b^2 = a minimum.  This is where I got stuck.  I have no clue what minimum for what function the problem is describing.  No one posted about this problem yet, so I'm assuming I just don't understand the problem.  Can someone help clarify?


Also, for the treasure problem, I took the derivative of the function then the second derivative.
I came up with: f"(x) = x^5 - 9x^4 + 24x^3 - 16x^2 .  I then set this function to zero to find the zeros, but it seems as if there's no way to find the zeros w/o a graphing calc?  Please help!

AB Clue Problem Set # 26

Hi! I need help on Set # 26 (Location). I integrate V(t) and it came out something like this: V’(t) = (1/3)t^3 - (39-6)t^2 + 40t + 4 Is that correct? And then… I got stuck.

i need help again

i need help on location problem for Set#19. What equation are we supposed to use?

help on #27 treasure

is this question where you use M/1+Ae^(-kt)?
and what do you do with the 600-P?
