It's a shame that sin and cos get lumped in with all the other trigonometry that you don't need to know, because the two basic formulas are incredibly useful and easy to learn:
x = distance * cos(angle)
y = distance * sin(angle)
Screw the rest. I learnt these as a kid writing a 2D computer game years before coming across them in high school maths.
