As before the problem doesn’t have negative eigenvalues If λ = 0, the general solution is X(x) = αx β so that 0 = X′(0) = β, implies that λ0 = 0 is an eigenvalue with the unique (up to multiplication by a constant) eigenfunction X0(x) ≡ 1If λ>0, then the general solution of the problem.

T u xx= 0 Shr odinger’s equation (18) It is generally nontrivial to nd the solution of a PDE, but once the solution is found, it is easy to verify whether the function is indeed a solution For example to see that u(t;x) = et x solves the wave equation (15), simply substitute this function into the equation (e t x) tt (et x) xx= e et x= 0.

T0(t) T(t) = k X00(x) X(x) −1 = λ, where λis a constant Then T0 = λT, X00 = k−1(1λ)X Conversely, if functions T and X are solutions of the above ODEs for the same value of λ, then u(x,t) = X(x)T(t) is a solution of the PDE For example, we may take λ= −1, T(t) = e−t, and X(x) = x Hence u(x,t) = e−txis the desired solution.
