### About this unit

In this unit we'll start by learning all about the law of sines and the law of cosines, which can help us figure out the side lengths or angles of a triangle. We'll also get to explore the unit circle, and how it connects to trigonometric functions like sine, cosine, and tangent. Finally, we'll have some fun graphing these functions and learning how to transform them. Get ready to get triggy with it!### Practice
