Good Morning everyone, I am stuck on a question that I can't get started so thank you for any help you give.

Derive the solution of the inhomogeneous wave equation on the half line using Stokes' Theorem via integrating over the domain of dependence.

$\displaystyle u_{tt}= c^2u_{xx} + g(x,t)$

$\displaystyle u(x,0)=h(x), \ u(0,t)=\xi(x), \ u_t(x,0)=\phi(x)$, $\displaystyle 0<x<\infty$

Can anyone help me please. Thank You for your help.
