What is the Unit Circle?
Before getting started graphing the sine and cosine functions, lets make sure you remember the concepts of the unit circle. Remember the unit circle consists of degree measures, radian measures, and coordinates. The coordinates are formed by the cosine and sine values at each degree or radian measure. The coordinates are the ( cosine , sine ) for each angle or radian. The lesson videos below go over how to form the unit circle with the degrees, radians, and coordinates.
