Functions

Cotangent= Adjacent/Opposite, graphed on the scale of pi, and it's inverse function is tangent.

Secant= Hypotenuse/Adjacent, groshed on the scale of 2pi, and it's inverse function is cosine.

Cosecant= Hypotenuse/Opposite, graphed on the scale of pi, and it's inverse is sin.

Tan= Opposite/Adjacent, graphed on the scale of pi, and it's inverse is Cotangent.

Sin= Opposite/Hypotenuse, graphed on the scale of 2pi, and it's inverse function is cosecant.

Cos= Adjacent/Hypotenuse, graphed on the scale of 2pi, and it's inverse is Secant.
