1. The problem statement, all variables and given/known data We have a 2-dimensional box with only one side at a potential V0. The other 3 sides are grounded. The box is a square with top and bottom at y=a/2 and –a/2 and sides at x=±a/2. Find V(x,y) (it should contain cos and sinh). 2. Relevant equations 3. The attempt at a solution I need help with this whole problem. Maybe if I get a start, I can work through it. Thanks.
