I was working through this problem,
I understand the method, but got stuck trying to differentiate the arc tan terms...
In the table of standard derivatives,
[tex]\frac{d}{dx} \arctan{x} = \frac{1}{1+x^2}[/tex]
and for PDE's, you treat y as constant when differentiating w.r.t. x
---
Any help greatly appreciated!
