A unit circle with trigonometric functions.
Sine, cosine, and versine of angle θ in terms of a unit circle with radius 1, centered at O. This figure also illustrates the reason why the versine was sometimes called the sagitta, Latin for arrow.[32] If the arc ADB of the double-angle Δ = 2θ is viewed as a
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.
