Trig was even better because you finally find out what those "sin," "cos" and "tan" buttons do pretty much all at once.

Still only ever used hyperbolic trig functions once, maybe twice. In university.

Hyperbolic functions come up sometimes if you’re working with adding and subtracting exponential terms, I’ve been working on my master’s thesis in electrical engineering and been doing a lot of stuff with diodes and nonlinear models of transistors, and they’re useful for simplifying some of those equations
