WebJul 9, 2024 · Consider the nonhomogeneous heat equation with nonhomogeneous boundary conditions: ut − kuxx = h(x), 0 ≤ x ≤ L, t > 0, u(0, t) = a, u(L, t) = b, u(x, 0) = f(x). We are interested in finding a particular solution to this initial-boundary value problem. In fact, we can represent the solution to the general nonhomogeneous heat equation as ...
