The well known trigonometric functions can be visualized on the circle of radius 1. See http://en.wikipedia.org/wiki/Trigonometric_functions for the definitions.
- Tangent: [math]\tan x = \frac{\sin x}{\cos x}[/math]
- Cotangent: [math]\cot x = \frac{\cos x}{\sin x}[/math]
- Secant: [math]\sec x = \frac{1}{\cos x}[/math]
- Cosecant: [math]\csc x = \frac{1}{\sin x}[/math]
