Question
Consider the following problem for the wave equation with periodic boundary conditions at a = 0:
Sozu = c8u, (x, t) €R x R,,
u(0, t) = cos(wt), te R..
a) Find at least one solution. Hint: use the solution guess E(a- ct) +n(a+ ct) and find a choice of
E,n that fits the BCs.
b) Is the solution unique or is there more than one?
