Question:Solving poisson equation

Hi there,

I am new to Maple. I need to solve a non-homogeneous partial differential equation (eg. poisson equation:

pd := expand(Laplacian(u(r,phi))=g(phi))

where g(phi)=Acos(phi)

 

My problem is that when I try to use the command  pdsolve, I get wrong answer. Cant maple solve a non-homogeneous equation directly? Do I need to guide it to solve the problem? How?

 

I am stuck with this problem for many days. :(

Any help will be much appreciated.

Thanks in advance.

Ira
