The names exsecant, versine, chord, etc. can also be applied to line segments related to a circular arc. [2] The length of each segment is the radius times the corresponding trigonometric function of the angle. The external secant function (abbreviated exsecant, symbolized exsec) is a trigonometric function defined in terms of the secant function:

In full analogy to the above-mentioned four functions another set of four "half-value" functions exists as well: The haversed sine [ 27 ] or haversine (Latin semiversus ), [ 28 ] [ 29 ] abbreviated haversin , semiversin , semiversinus , havers , hav , [ 30 ] [ 31 ] hvs , [ nb 2 ] sem , or hv , [ 32 ] most famous from the haversine formula used ...
Sec-1, SEC-1, sec-1, or sec −1 may refer to: . sec x−1 = sec(x)−1 = exsec(x) or exsecant of x, an old trigonometric function; sec −1 y = sec −1 (y), sometimes interpreted as arcsec(y) or arcsecant of y, the compositional inverse of the trigonometric function secant (see below for ambiguity)

Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) [1] are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
This is a list of some well-known periodic functions. The constant function f (x) = c, where c is independent of x, is periodic with any period, but lacks a fundamental period. A definition is given for some of the following functions, though each function may have many equivalent definitions.
