Question 546665: State the reference angel associated with each rotation, then find the associated point (x,y) on the unit circle. Express non-integer values in the answer as reduced fractions, if necessary.
theta = 5pi/3
5pi/3 is in which quadrant?
so the point is ?

2pi is a full circle ___ 2 = 6/3 ___ so 5pi/3 is 5/6 of a circle or 300º ___ quadrant IV ___ this is a 60º reference angle

x = cos(-60º) ___ y = sin(-60º)
