 * =Brief Summary of Unit= ||
 * This unit is discussing the ability to use the basic unit circle to be able to derive the sin, cos and tan at different ratios. Students will then learn there is a difference between radians and degrees. Students will learn how it is posssible to convert back and forth between each of these. In this section there will be a focus looking at the graphs of tan, sin and cos and how they compare and differ from one another. Later in this unit students will be able to see what the meaning of sin, cos and tan are related to each right triangles. There will be a quick lesson on how to use arcsin, arctan, and arccos and show how they are used. After all of this students should be able to comprehend and understand the basics of trignometry. ||
