Hi everyone. I could really use a hand with this question:

Thank you to anyone who can help. Sorry if this is in the wrong section.Solve the one-dimensional wave equation:

(∂^{2}u/∂t^{2}) = c^{2}(∂^{2}u/∂x^{2})

Where c is a non-zero constant, subject to the boundary conditions:

u(0,t) = u(l,t) = 0, _____ t ≥ 0

And the initial conditions:

u(x,0) =

x/5_____________ 0 ≤ x ≤ 1/2

(1-x)/5__________1/2 ≤ x ≤ 1

(∂u/∂t)_{t=0}= 0, 0 ≤ x ≤ 1
