The following PDF contains some notes I prepared and modified slightly for posting here. Its been modified to compliment Hootenanny[/color]'s differentiation thread. Many thanks to Hootenanny[/color] for reviewing it along with Dr. Transport[/color] and rbj and others.

As ever, any comments, corrections/suggestions can be directed to me by private message.

Corrections will be posted in this thread. Hopefully there won't be too many. :smile:

That's awesome.. good work Kurdt!
 
Just a note to remind users that this is an informal reference and shouldn't be used as a students only resource for learning.
 
Shouldn't there be some absolute value signs in the section dealing with trigonometric substitution?

You'll need to be more specific than that! :wink:
 
In the middle of page 8 (:wink:), it says that \sqrt{a^2\cos^2x}=a\cos x.
 
There should be an updated version coming soon with a few corrections.
 
Great work, Kurdt. THANKS!

Thank you for this, I will read through it since this is my study level right now.
Is this something I can rely on though, as fully accurate?

As I have said in a previous post, this is something that should not be used by itself by students. It is made to supplement textbooks and course notes as more of a quick reference guide. Some people have already pointed mistakes out and that's why I'm working on an updated version (when I get the time). If you spot any please post them in this thread.

You might also mention a more generalized version of FTC:

If F(x) \, = \, \int_{g(x)}^{h(x)} f(t) \, dt, then F'(x) \, = \, f(h(x))h'(x) \, - \, f(g(x))g'(x)
