Q4(a) Find a formal solution to the one-dimensional wave equation governed by the given initial-
boundary value problem.
49UXX = Utt
0 <x< 5, t>0
(a) u (0, t) =u (5, t) = 0,
(b) и (х, 0) — 0,
(с) u (х, 0) 6.
(b)
Find a formal solution to the heat diffusion problem by the given initial-boundary value problem.
Solve the final answer for each of the given different initial conditions.
Uxx = Ut
0 <x <T,
t>0
u (0, t) = u (n, t) = 0,
0<x <n
u (x, 0) = 3sin 2x - 6sin 5x + 10 sin 7x,
и (х, 0) %3D х?, 0<x <л
