The Weird Integrals

I made a PDF of the "weird" integrals, except I don't know how to put PDFs up here! So I just made a jpeg of the PDF, even though PDFs are cooler. I'm not sure about the integral of secant, by the way.

I need help on #2

Hi guys.
Does anyone know how to do #2 on today's homework (HW#8). I tried to do it in different ways, but I keep getting different answers and they all don't match with the one on the answers.
Thanks!

More info

You are free to choose a section homework in the future that you want to be the "go-to-guy or girl" for. You'll have to work on the assignment early (with my help on getting the lesson ahead of time as well) and then the next day after the homework is assigned, you'll be the one to answer people's questions.
Hopefully you can sort of model how I do it, where you don't always have to finish solving the entire problem, but rather help the others on how to get started.

Okay, so how about this?

Whoever's interested in being the person who answers HW questions (hmm, help me come up with a name for this 'job') send me an email or post it on here. Any upcoming section (unless I veto it) is fair game. I am willing to help you ahead of time so that you are comfortable enough with it all.
Extra-credit for doing this will be calculated by the class average for the opener on that section. So up to 9 points.

Any Interest?

Trying to come up with alternative 'challenging' things for possible extra-credit:

• working with me and working ahead to 'knowing' a section well enough to teach it
• knowing the HW well enough to answer questions about them (but there has to be a time limit so a new lesson can still be introduced

I don't know...it would be tough, but doable. Tough in that you'd have to work out the problems ahead of time and know it well enough to field questions.
If there's an interest, how do I choose?! Randomly?

Other ideas?! I don't want useless stuff. No fluff. It would not and could not be something 'easy'. It has to be earned.

Anyhow. I'm willing to hear suggestions.
Oh! Many of you may like this first part of chapter 6...starting Friday we'll simply be practicing a skill. Namely integration. None of that confusing word problem stuff.
Hehe. That all comes later!

Review Questions

Heey,
For the hw assignment, I'm just wondering why do we flip the 1 and negative 1 for question 54 c. (for question 54 g the minimum one as well). Isn't it above the x-axis? If you can answer it, thanks.

For number one, I keep getting instead of .
Correct me if I'm wrong, but I think .
So then MRAM would equal .
I worked at this for a really long time and decided to check with my graphing calculator on the INGRL program and the answer I got was 1.41609, which is equivalent to .
Please let me know if I'm doing something wrong.
Thanks!

I will be better!

I apologize to 1st period...I haven't been doing a good job with you the last 2 days. I've spent too much time on talking about stuff that's 'easy' and then not had enough time at the end to finish everything I need to say. This time I found it happening TWO days in a row. I promise I will work harder to not repeat this.
Umm, why am I only apologizing to 1st period? Well, I learn from what I did 1st and try to make sure I don't repeat it 3rd period...Sorry...
I PROMISE to look over my notes MORE CAREFULLY before hand so that I don't do this again (umm, or this bad).

I still feel like I'm crawling my way back into the classroom...and I know that's no excuse. I'm running back now!!
