Yeah, where they do some shit like
<span class="math">p \psi \to -i\hbar \, \partial \psi / \partial x = -i\hbar \partial e^{i(kx-\omega t)} / \partial = -i\hbar (ik) \psi = \hbar k \psi = p \psi[/spoiler].
Which is great and all, but it assumes <span class="math">\Psi[/spoiler] is always of that form.
And now that you guys say it, since any function can be broken down to linear combinations of complex exponentials, then I guess that would still work.

Hm, I actually might be able to loosely follow that kind of proof. I haven't had Group theory yet, but I've had a shitload of linear algebra; and as I understand it, a group is just a vector space with an additional associated operation -- I could be way off though.

Pic related! It's a joke of course... but still
