IfStill doesn't work!
Anyway, he was working with . He said that if , then the indefinite integral is equal to . This is what I missed to understand. Did he do integration by parts? How could he reach this result? Thanks!!
Then
Now let
I must find for which values of the following integral converges : . Mathstud28 already done that (well, something pretty similar) in one of my earlier threads, but I didn't understand a step he did, so I would like a little bit more explanations :

Hmm, sorry the quote doesn't work. I copy and past it, but it only shows the first line and all the other is cut, so I quote it by parts :[quote].

This is mathstud's baby, so I will leave him answer. I am sure he is typing as I write this. Anyway, here is a site with a list of integrals you may find helpful instead of deriving them each time. Unless you want to.
