I'm not entirely sure what you are trying to integrate.

If you're trying to integrate , that just equals . At this point, let and . Thus and . Thus your integral becomes . Thus the answer is .

If you're trying to integrate , let and . Thus, and . Thus, your integral becomes = . Now you can do a u-substitution. Let so that . Subbing in leaves you with . Thus the answer is .

I hope that one of these was what you're looking for.
