The unit circle is a circle of radius 1, centered at p0, 0q. It is used as a way to keep track of sine and cosine values of important angles.

Students will discuss the unit circle and take notes on their unit circle page. • A circle with r = 1, and center is (0, 0). •. •. Equation: x² + y² = 1 siny ...
