I can only think of two scenarios where high school math would come in handy

1

MURDERER: I’m a crazy person. Do this trigonometry problem or I’ll murder you.

ME: Can I use a graphing calculator?

MURDERER: Yes, of course. Oh – and here’s a list of necessary formulas.

ME: Great, thanks. Okay, let’s see … sin2x = 2cosxsinx?

MURDERER: That’s correct. You’re free to go.

OLD RICH MAN: Hello, everyone. I’ve gone completely insane. Whoever solves this trigonometry problem fastest gets all of the money in my will.

ME: Can we use graphing calculators?

OLD RICH MAN: Yes – and the necessary formulas are on the second page.

ME: Cool. Is it t = 50?

OLD RICH MAN: I need it expressed to me in radians.

ME: t = 0.28?

OLD RICH MAN: Congratulations, here is all my money.
