a cylinder region with square cross section has the following potential distributions on its four walls:

a cylinder region with square cross section has the following potential distributions on its four walls:

v=0 at x=0 and y=0

v=V0* sin(pi/a)*x at y=a

v=V0*sin(2pi/a)* y at x= a

The interior region is free of charge.Find the potential inside the cylinder space(0<x<a,0<y<a).

[HINT]Use the superposition of two boundary value problems.
