2. a. Show that the general solution of the PDE $u_{xy} = 0$ is $u(x, y) = F(x) + G(y)$ for arbitrary differentiable functions $F$, $G$. b. Use change of variable $\xi = x + t$, $\eta = x - t$ to show that $u_{tt} - u_{xx} = 0 \iff u_{\xi\eta} = 0$. c. Use a. and b. to rederive d'Alembert's formula.
