I am trying to solve poisson equation: diff(diff(u(y,z),y),y) + diff(diff(u(y,z),z),z) = 1 using separation of variables method. The boundary conditions for the problem are: u(1,z)=0 u(-1,z)=0 u(y,1)=0 u(y,-1)=0 can you please guide me to a good reference which will help me in solving this problem using separation of variables. Do you know how to solve this equation using mathematica
