I don't know what sin x, cos x or f(x) means. What books do I need to read to fix this? Teacher is making us solve shit like this and I have no idea what I'm looking at.

You want to look at a book called "trigonometry" and maybe add in some additional pre-calculus

...anon, this is PDE’s. How the fuck are you in a PDE’s class without knowing what sinusoidal functions are

Can you just tell me what books I need to read, so I can solve equations like in the pic.

This is not a PDE, it's just a function whose partial derivatives have been calculated
