Is there a good way to do Laplacian when the function in question is a function of functions, like in the L2 gradient examples?

This wouldn't always happen, right? It's just by nature of the function being in terms of the sinusoids and their second derivatives are just the opposite of the original function, and the derivative of what's inside the sin/cos functions are scalars in this case.
