Web1 Take an eigen vector v corresponding to an eigenvalue λ . Use this fact and cacluate A 2 v and 6 A v independently, and equate them using the information A 2 = 6 A; that will give you a condition on λ enabling you to guess it.

In other words X ″ (x) + λX(x) = 0, T ′ (t) + λkT(t) = 0. The boundary condition u(0, t) = 0 implies X(0)T(t) = 0. We are looking for a nontrivial solution and so we can assume that T(t) is not identically zero. Hence X(0) = 0. Similarly, u(L, t) = 0 implies X(L) = 0.
