Solving Dirichlet BVP by Eigenfunction Expansion

  1. Hey all, I have a question about the following problem:

    say that the domain omega is [0,pi] x [0,pi]
    Solve the equation –Δu=1 for x in omega, and u=0 for x in the boundary of omega;

    Just curious whether supposed to use eigenfunction expansions? And how to solve?

    Thanks!
