Question
please help me answer this as the wording is confusing to me.
1. how do you find the exact value of the sine as well as the cosine of any angle (you pick one) in quadrant II, III, or IV that has a reference angle of pi/3, pi/4, or pi/6.
2. now clearly sketch as well as indicate your angle and you may assume you know the points on the unit circle at angles of pi/3, pi/4, or pi/6.
