## Eleventh grade Lesson The Unit Circle Day 1 of 2.

Unit Circle. What you just played with is the Unit Circle. It is a circle with a radius of 1 with its center at 0. Because the radius is 1, we can directly measure sine, cosine and tangent. Here we see the sine function being made by the unit circle: Note: you can see the nice graphs made by sine, cosine and tangent. Degrees and Radians.
