Use separation of variables to find a series solution of utt = c 2uxx subject to u(0, t) = 0,
ux(l, t) + u(l, t) = 0, u(x, 0) = φ(x), & ut(x, 0) = ψ(x) over the domain 0 < x < `, t > 0. Provide an equation that identifies the eigenvalues and sketch a graph depicting this equation. Clearly identify the eigenfunctions
