secant, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is sec A = length of hypotenuse/ length of side adjacent angle A. (The other five trigonometric …
Trigonometric functions - Wikipedia
The word tangent comes from Latin tangens meaning "touching", since the line touches the circle of unit radius, whereas secant stems from Latin secans —"cutting"—since the line cuts the circle.
Secant function (sec) - Trigonometry - Math Open Reference
In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'.

Secant Formula - What is Secant Formula?, Examples - Cuemath
When the length of the hypotenuse is divided by the length of the adjacent side, it gives the secant of the angle, of the right-angled triangle. Secant is denoted as 'sec'.
SECANT | definition in the Cambridge English Dictionary
If from a point without a circle a secant is drawn, the product of the secant and its external segment is constant in whatever direction the secant is drawn.
Secant and Cosecant - Algebrica
Nov 22, 2025 · The secant function f (x) = sec (x) is defined as the reciprocal of the cosine function. It assigns to each angle x (measured in radians) the value 1 / cos (x).
