    1. The problem statement, all variables and given/known data

    struggling with a problem and hoping someone could help me out. the problem reads,

    Let F and G be arbitrary differentiable functions of one variable. Show that u(x,t) = f(x+ct) + G(x-ct) is a solution to the wave equation, provided that F and G are sufficiently smooth.

    thanks in advance
