High Quality Content by WIKIPEDIA articles! In mathematics, the trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications. The versine or versed sine, versin(?), is a trigonometric function equal to 1 ? cos(?). The versine function appeared in some of the earliest trigonometric tables and was once widespread, but it is now little-used. It is also written as vers(?) or ver(?). In Latin, it is known as the the sinus versus (flipped sine) or the sagitta (arrow).
