Hi guys, this is my first time posting, I'm studying physics at uni, in my third year and things are getting a bit tough, so basically my question is in relation to solving problem 1, (i included a picture...) I missed the class and don't really know what I'm doing. Any help would be appreciated.

That's an elementary problem in peturbation theory, you can't expect us to explain everything here.
Just read over the chapter, there is a very nice formula for it.
 
Sorry to trouble you then.
