Sorry about the late response here, but I've been messing with the problem
Thank you all for your help!
I actually looked up trig substitution, and it's 2 sections after this one (hopefully it makes dealing with this stuff easier ). I also need to get use to maple, I got , and I kept on comparing it to the answer maple got, and it kept showing me false. I finally just did the derivative of my answer, and then simplified it and got . So then I played with the answer maple gave me and simplified it symbolically, and it gave me the same answer as I got.
I guess I should RTFM
lol, thanks again guys!
