## Homework Statement

∫√(2+cos

^{3}(t)) dt

I should perhaps have tried to get the lower and upper limits of this integral (it's defined), but all I'm wondering about is how to calculate the integral. I don't need the answer, but if someone could just point me in the right direction. I've tried "normal" substitution, but I can't find a smart u :P

I appreciate any hints :D

PS! I'm Norwegian, and so my mathematical formulations might be slightly off, I'm used to write this stuff in Norwegian, haha:)
