Problem 2 (Chapter 7; 60 points) Solve the following Laplace's equation in a parallelepiped, carefully explaining all steps. Make sure to check for zero eigenvalues. Note that the single non-homogeneous boundary condition is on the y-plane (y D). The boundary conditions are simple enough so that all Fourier coefficient integrals are easily calculated. You don't have to give details in the solution of the two LHBVPs, but make sure to check all boundary conditions after you find the solution: ou...
