# How do you find the coordinates of the terminal points corresponding to the following arc length on the unit circle: -5π/3?

x of terminal point: $x = \cos \left(\frac{- 5 \pi}{3}\right) = \cos \left(\frac{\pi}{3}\right) = \frac{1}{2}$
y of terminal point: $y = \sin \left(\frac{- 5 \pi}{3}\right) = \sin \left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}$
