1. ## PDE question

Utt - Uxx = sin(t)

U(0, t) = 0
U(1, t) = sin(t)
U(x, 0) = 0

Ut(x, 0) = 0

2. How about posting the ENTIRE problem if you want HELP.

3. ## here is the rest

Solve the following PDE: wave equation with forcing and non homogeneous boundary condition:

Utt - Uxx = sin(t)

U(0, t) = 0
U(1, t) = sin(t)
U(x, 0) = 0

Ut(x, 0) = 0
