# Trigonometry

## Explore trigonometry through identities, polar graphing, and solving triangles.

This course will teach you the all of the fundamentals of trigonometry, starting from square one: the basic idea of similar right triangles. In the first sequences in this course, you'll learn the definitions of the most common trigonometric functions from both a geometric and algebraic perspective.
