Introduction

The unit circle has a center a (0, 0), and a radius of 1 with no defined unit.

Sine and cosine can be used to find the coordinates of specific points on the unit circle.

Sine likes y, and cosine likes x.

When sine is positive, the y value is positive. When x is positive, the cosine is positive.
