Question

How do you find the coordinates of the terminal points corresponding to the following arc length on the unit circle: 11π/6?

Answer 1

Part 1: If you are okay with `11pi/6 = -pi/6` go to Part 2.

Part 2: If you are okay with standard side lengths of triangles with angles `pi/3` and `pi/6`, go to Part 3.

Part 3:

Coordinates of the required terminal point are
`(x,y) = (sqrt(3)/2, -1/2)`
