## Homework Statement

Hi guys

Please take a look at the second question in 10.20 (the question with the diff. equation):

http://books.google.com/books?id=Mq...ts=JOvnmWE-Jo&sig=FP2sASpndHBj_ETidnKSzSxsFd4

I have found the expression for the operator E, but how do I show that f(r) satiesfies the diff. equation?

## The Attempt at a Solution

First thing would be to insert "psi"(r,theta) in E - but where to go from here? I am very lost.

Thanks in advance,

sincerely Niles.
