Finding reduction formulas for u^n integrals

[tataraperz]

Homework Statement

Well, I've been doing a lot of research about the reduction formula as a method for resolving integration problems. However, not much information on the topic is to be found about the topic. The only things i get to find are examples with the formulas already given, which is cool, but still not what i need.

The Question is ¿is there a general method to find the reduction formula for any given u^n function?
Thanks.

It depends on the function it self.
Personally, I think integration by parts is the famous way of finding the reduction formulas.
