Subject: On Laplace's Equation

Let us consider Laplace's equation with azimuthal symmetry

The solution is given by:
psi[r,theta]=summation over n [from zero to infinity] [An r^n+ Bn r^{-
(n+1)}]Pn[Cos(theta)] ----------- (1)

An and Bn are constants.Pn stands for Legendre-polynomials. "n" is a
suffix.
Now we look for a an elementary solution of the same equation in the
form

psi=An f(psi) r^n +Bn r^{-(n+1}}
Substituting the above "psi" into the original equation[Laplace's
Equation with azimuthal symmetry] we may obtain expressions for f.

So we have a different solution now.The general solution obtained by
summing up these new elementary solutions may cover a broader range of
boundary conditions, uncovering new types of solutions.
