Lesson Plan: Unit Circle and Triangle

By

Unitcircle_3 This lesson develops the Unit circle of radius 1, x-axis and y-axis sketched on the unit circle and compares how these values are the solution to cosine and sine. The x coordinate of a hypotenuse of a right triangle on the unit circle is its cosine value. The y coordinate of the hypotenuse of a right triangle on a unit circle is its sine value.
