(1) You're going to need to use integration by parts twice.

First round requires: and

You will get:

Use integration by parts again on the red: and

Can you carry on from here?

(2) Again, you'll need integration by parts: and

You'll get:

The blue integral should be easier to deal with now. You'll need long division or you can notice that: - Jan 21st 2009, 11:44 PMDeMath
