I need to do this without using complex numbers. Working with the fraction: Back to the integral: Assuming I made it this far correctly, I'm not quite sure what to do with the second integral... obviously the first is

integral of the first fraction will be integral of the second will be

Try to take it from here. --Chris
Basically split up your fraction into two:
I didn't check your work but you can use a trig substituion to solve the integral you are having difficulty with.
Looking back through my text, I realized I breezed over that section a little bit too quickly. Splitting into 2 integrals was what I missed. Anyways, I got the right answer, thanks everyone for your help!
without partial fractions: ............................ ............................ ............................
Haha, it seems you started to give short answers, that's good, keep it up!
