Answer:
(srt(3)/2, -1/2)
Step-by-step explanation:
x = rcos theta
r = 1 on unit circle
x = 1 cos (-pi/6)
x = sqrt(3)/2
y = r sin theta
y =1 sin (-pi/6)=
y = -1/2
The numerator and denominators will have no common factors.
For example 4/6 is not in its simplest form because both 4 and 6 can be divided by 2. In simplest form this will be 2/3.
