WebTo solve this problem using the eigenfunction expansion method, we first need to find the eigenfunctions and eigenvalues of the Laplacian operator on the unit square with zero boundary conditions. The Laplacian operator in two dimensions is given by: Eigenfunctions can be expressed as column vectors and linear operators can be expressed as matrices, although they may have infinite dimensions. As a result, many of the concepts related to eigenvectors of matrices carry over to the study of eigenfunctions.
