What is Eigenfunction Expansion for PDE Solutions about?
This document discusses using eigenfunction expansions to solve nonhomogeneous partial differential equations, specifically the nonhomogeneous heat equation. It presents the eigenfunction expansion approach, where the solution is expressed as an infinite series involving eigenfunctions, and the expansion coefficients are functions of time. The initial condition, boundary condition, and nonhomogeneous term are also expanded in the eigenfunction basis. Plugging into the PDE yields an ODE for each expansion co
