Ah, I have seen that before in another class! I think I understand now. Thank you, thank you!

I honestly have no idea. I know that you have to relate $u(x,t)$ with $w(\xi,\tau)$ and then use the chain rule. If you could help me with finding one derivative, like transforming the term $u_t$ I will try the others on my own. Thank you for your reply

For quick reference if you have the text, the question is from "Applied Partial Differential Equations" by J. David Logan. Section 1.9 #4 Show that the equation $$u_{tt} - c^2 u_{xx} + au_t + bu_x + du = f(x,t)$$ can be transformed into an equation of the form $$w_{\xi\tau} + kw = g(\xi,\tau)...
