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.

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,

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?

AB Review Treasure 13

Did anyone get Treasure 13 with the equal areas under the curve? When I integrate I end up with a quartic equation that I can't solve by hand, and I don't see how it can be simplified down. Does anyone know how to solve the equation?
Sorry about the previous post. I meant Treasure 13 instead of Location 13 and don't notice until Priya responded.

I need help!!!!

Did anyone do the suspect problem for Set#19. I did it a couple times but I can't get an answer that makes sense. Can someone help me?

AB Review Location 13

Does any one know how to solve location 13? I can't solve the quartic equation I end up with for k. There's no use of graphing calculators and it doesn't seem like the equation can be factored. I don't see any way to simplify the equation and so far the rest of my work seems right. Did any one get an answer?

Calc AB Review Question

Did any one else get a negative answer for any of the review questions? I seem to get a negative answer for Location #4. I think I've done something wrong since I haven't used the interval on this problem, but right now I don't see any other way to approach this problem. I'm pretty sure none of the answers are supposed to be negative. Did anyone else have this problem?

FR SET #5 1990 AB3

Hi, I am Michael Cupino from period 3. In FR Set #5 1990 AB3, I understand all the concepts of finding area and finding volume. Only thing that I couldn't do was solve for x, which is probably an Algebra thing, but I'm having a hard time finding x without using a calculator.

y=e^x, y=(x-1)^2
I'm having trouble solving for x.

e^x=(x-1)^2

"ln"ing both side did not help. I can find out where they intersect on the calculator, but this is the no calculator part. So it'd be great if someone could go over this little algebra problem.

Openers

Is there going to be an opener tomorrow for the AB review? If so, what kind of material is going to be on it because the AB was a mix of things. Please let me know.
And also, Mrs. Carlson, is there any source of extra credit possible for first semester to help those in need?
Thank-You

Need Help on Chapter 8 review

On the Chapter 8 review, can someone explain number 21 for me. The part where they make x into (1/x). It's toward the end. It would be very helpful.
Thank-you. Jennifer Oh
