QUESTION:

Approximate the solution to the following partial differential equation using the Backward-Difference method. u t 1 16 2u x2 = 0, 0 < x < 1, 0 < t; u(0, t) = u(1, t) = 0, 0 < t, u(x, 0) = 2 sin 2x, 0 x 1. Use m = 3, T = 0.1, and N = 2, and compare your results to the actual solution u(x, t) = 2e(2/4)t sin 2x.
