Eigenvalue PDE? How can I solve for lambda of the new problem exactly how the old problem was solved. Both problems are included in the attached picture. Please show steps

any chance you could upload a version of that image that doesn't require a microscope to see?

And opening THAT requires one to have Microsoft Office on your computer! Using a magnifying glass to read the first post, the first problem given is the boundary value problem with boundary conditions u(x, 0)= u(x, W)= 0, u(0, y)= u(L, y)= 0. The "suggest" first solving the eigenvalue problem . The question, then, is "why doesn't that same eigenvalue strategy work if the boundary value problem is with boundary conditions u(x, 0)= u(x, W)= 0, u(0, y)= u(L, y)= 0."
