#### Right triangles & trigonometry

We'll learn about the different trigonometric ratios – sine, cosine, tangent, cotangent, secant, and cosecant! We'll learn about inverse trigonometric ratios and briefly discuss radians/degrees. Finally, we'll solve practice problems together and answer any of your questions. This session is intended for people who aren't familiar with trigonometry or want to review the basics. Please come prepared with a calculator!

#### Right triangles & trigonometry

Intro to the UNIT CIRCLE!! We will go through radians and then what the coordinates mean. And after that, if we have time, I will go through some of the 45-45-90 and 30-60-90 special triangle proofs.
