I'm currently working on a 2D Finite Difference code in MATLAB and am trying to check the approximations with the exact solution. Unfortunately I don't know how to employ the Galerkin Method to solve the given equation for exact results. Problem statement is attached. Any help is appreciated on solving this 2D problem.

In case the picture is unclear, (∂²u/∂x² + ∂²u/∂y²) + uk² = xk² u = u(x,y) u is a function of x and y Boundary conditions are zero of the square domain (0,1)×(0,1) Determine an exact solution in the form of a sine series expansion by employing the Galerkin Method.
