How i looked at it was the temperature at the center of the disk could no approach infinity so i eliminated the e^n term. Since the Distribution is based on a cos^2 term maby we can eliminate the sin term as well. Giving us u = c_1e^{-n}cos(n \phi) where c_1 is some constant. Not sure where to...
Homework Statement
A circular disc of radius a is heated in such a way that its perimeter r=a has a steady temperature distribution A+B \cos ^2 \phi where r and \phi are plane polar coordiantes and A and B are constants. Find the temperature T(\rho, \phi) everywhere in the region \rho < a
