[SOLVED] Laplace equation, cylindrical 2D
I am given the Laplace eq. in cylindrical coord. (2D), and I am told that we can assume the solution u(rho, Phi) = rho^n * Phi(phi).
Find the general solution.
My teacher says that the general solution is u(rh,Phi) = SUM [A*cos(...) + B*sin(...)]*rho^n.
It is tis version of the Laplace equation on the first equation on page 12 in here:

Why do we not differentiate rho?
