Anyone having an idea of how to solve problem 3a) file:///C:/Users/Administrator/Downloads/handin1%20(2).pdf ?

I've been stuck for a great while but have not idea.

on part 3b) is it correct to argue that since you integrate away the x-dependence in the number operator that according to the Heisenberg equation [H,N]=0 since both the partial derivative and total derivative of N is zero?
 
You know, I'm having a great deal of difficulty reading that file. :w Maybe you could hold it up a little closer to *my* screen?
 
Why can't you read the file? file:///C:/Users/administrator/Downloads/handin1%20(2).pdf

Because it's on your computer!
