Integral Question

[uberathlete]

Hello again everyone. I'm stuck with this integral problem:

int [sqrt(x)] / (2x^2+1)

I've tried letting u = x^2 but it's not working out too well. If someone could point me to the right direction it's be much appreciated. Thanks!

I'm thinking you have a tangent in your future.

What a subtle hint, heh. Assuming this is workable (the answer from my CAS was huge), inverse trig functions and partial fractions might do the trick.

True true. I tried it on Maple and the answer was quite big. I was like :shock: . I'm wondering how the ln() got in there. I still can't seem to crack it :?
