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. (It's well known that you can shake a stick at a maximum of 8 trig functions.) The familiar sine, cosine, and tangent are in blue, red, and, well, tan, respectively. The versine is in green, and the exsecant is in pink. Excosecant and coversine are also in the image.
