Question

Explain how to use the unit circle to find sin 180°

Answer 1

0

Explanation:

We know sin is the y placement in coordinates. ex: (x,y) or (cos, sin).

We also know that 180° is a straight line. So, when we move over 1 unit that makes our x= 1 (or cos(180 degress) = 1). When we only move over 1 but not up or down that makes our y = 0 (or sin(180 degrees) = 0)
