Circular Functions
The functions describing the horizontal and vertical positions of a point on a Circle as a function of Angle(Cosine and Sine) and those functions derived from them:
 |  |  | (1) |
 | |  | (2) |
 | |  | (3) |
 | |  | (4) |
The study of circular functions is called Trigonometry.See also Cosecant, Cosine, Cotangent, Elliptic Function, Generalized Hyperbolic Functions,Hyperbolic Functions, Secant, Sine, Tangent, Trigonometry
