WebJun 15, 2024 · First we plug u(x, t) = X(x)T(t) into the heat equation to obtain X(x)T ′ (t) = kX ″ (x)T(t). We rewrite as T ′ (t) kT(t) = X ″ (x) X(x). This equation must hold for all x and all t. But the left hand side does not depend on x and the right hand side does not depend on t. Hence, each side must be a constant.
