# Tan Unit Circle

10 Secret Trig Functions Your Math Teachers Never Taught You...(because they are from a pre-calculator world) A diagram with a unit circle and more trig functions than you can shake a stick at.

The versine is in green, and the exsecant is in pink. Excosecant and coversine are also in the image.
