oooof,, u pple need something do to anything. I find it more interesting doing it by hand. first of all it gives pratice doing integrals, and then it also gives confidence

[Bryn]

yes i'm trying to do it by hand, but the book i'm working from is riddled with mistakes, i dunno if i'm doing it wrong or if the book is giving mostly wrong answers.

Could try something like http://integrals.wolfram.com/
