Consider the ODE y"-k²y = f(x) 0≤x≤1 k > 0 with boundary conditions (a) (b) y(0) = 0 y(1) = 0 Compute the Green's function G(x, x') for this ODE. That is, solve the boundary value problem d²G - k²G(x, x') = d(x − x') dx2 with boundary conditions G(x = 0, x) = 0 G(x = 1, x') = 0 and where 8(x) is the delta function. Use the Green's function developed in part (a) to solve the inhomo- geneous boundary value problem = y"-k²y 10≤ x ≤1 k > 0 with boundary conditions y(0) = 0 y(1) = 0 You may leave your answer in terms of integrals.
