Unit Circle Trigonometry Cheat Sheet
This is my version of the unit circle on steroids. I have tweaked it over 10 years and finally created the perfect teaching tool to fit on one page!
I have included a symbolic key for the range of inverse functions, alongs with information on Tangent and reciprocal identities.
Two versions of the unit circle are included, one with and without hand trick notes.
A separate page contains detailed notes on the hand trick that I like to use for memorizing the unit circle trigonometry facts. This trick is especially valuable for students who have a difficult time committing the trig facts to memory even after drawing countless number of special right triangles.
I like to place this sheet in a page protector to use as a dry erase tool. This is quite helpful when learning about coterminal and reference angles. I also stress the fact that a unit circle has a radius of one, so that quadrantal angles values are easily memorized.
