Hi,
Looking for help on what to do next.

Question (it's in two parts but part 1 is like two lines):
Part 1: http://imgur.com/BwyNwsE [1]
Part 2: http://imgur.com/LrIh4IP [2]

Normally my approach is to evaluate the double derivative on the LHS and rearrange until I can equate it to the RHS. This time I'm unsure what to make of Φ as it's not expressed in terms of x and y.
What am I looking at and how do I go about solving it?
Thanks.

Take the given $\psi(x,y,z)$, substitute it into the (3-dimensional) time independent S.E., and evaluate whatever derivatives you can evaluate.
