>mostly just manipulating integrals. They almost always teach convolution too, which is an operation that has an unwieldy integral definition if you're not used to it.
More stuff to study then!
>Differentiation in time is equivalent to multiplication by the frequency variable ωω \omega , so by converting your equation into FTs, the ODE becomes a simple algebraic equation. All you need to do is solve for the FT of your function (trivial), and then convert your answer back from FTs into function of time.
What the hecc, since I'm currently just starting differential equations, this sounds like cheating and is super useful. Sorry I didn't understand the stuff you said before tho, but soon I will...
>my circuits fundamentals are fucked because of a really shitty prof
Heh, same, now I'm dying in a class that uses it.

Is there any signal processing textbook/resource you'd recommend? I'm always getting interested in new things because EE is so freaking massive.
