## Unit Circle Display

I created these unit circle magnets to use with my dry erase magnetic unit circle from EAI Education. I plan to use the magnets both as a way to have a large unit circle on the wall of my classroom and for various activities throughout the year.

## Trig Functions Posters

I created these trig functions posters a few years ago when I was teaching a year-long trigonometry course. I created separate posters for the three basic trig functions and the three reciprocal trig functions. I designed these posters to print on 11 x 17 cardstock.
