Versine

A unit circle with trigonometric functions.

The trigonometric functions can be constructed geometrically in terms of a unit circle centered at O.

Comparison of the versine function with three approximations to the versine functions, for angles ranging from 0 to 2π

The versine or versed sine is a trigonometric function already appearing in some of the earliest trigonometric tables. The versine of an angle equals 1 minus its cosine.

There are several related functions, most notably the coversine and haversine. The latter, half a versine, is of particular importance in the haversine formula of navigation.
