Thanks! I think I may have gotten it, not 100% sure though, got class soon so i'll find out then. Thanks again

Hmm yeah that probably is the best choice, I tried it earlier but am still hitting a wall u = x^2 du = 2xdx 1/2du = xdx 1/2INTEGRAL (Ue^U) / (U+1)^2 dU Can that be integrated? I've always been so bad at knowing when I can do something and when I can't, it kills me on tests.

I've been going at this problem for at least 3 hours :cry: Just need to find the integral for: INTEGRAL(x^3e^x^2) / (x^2 + 1)^2 dxI've tried all kinds of different methods, filling up at 4 pages in my notebook! I think this is the closest I've gotten :confused: First I broke up the numerator...
