Secant | Definition, Formulas, & Facts | Britannica
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 functions are sine [sin], cosine [cos], tangent [tan], cosecant [csc], and cotangent [cot].)

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 - Wikipedia
Secant is a term in mathematics derived from the Latin secare ("to cut"). It may refer to: a secant line, in geometry the secant variety, in algebraic geometry secant (trigonometry) (Latin: secans), the multiplicative inverse (or reciprocal) trigonometric function of the cosine
Secant Function - Formula, Graph, Domain and Range ... - Cuemath
The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle. It is the reciprocal of cosine function and hence, is also written as sec x = 1 / cos x.
Secant — Definition, Formula & Examples - Mathwords
Secant is the trigonometric function defined as the reciprocal of cosine. Written sec θ, it equals 1/cos θ and is undefined wherever cosine equals zero.
Secant Formula - Concept, Formulae, Solved Examples
Secant is one of the six basic trigonometric ratios and its formula is secant (θ) = hypotenuse/base, it is also represented as, sec (θ). It is the inverse (reciprocal) ratio of the cosine function and is the ratio of the Hypotenus and Base sides in a right-angle triangle.

Secant Defined: What Is It Over What in Trigonometry?
🚀 TL;DR – Key Takeaway The **secant** in trigonometry is the **reciprocal of cosine**—meaning it’s calculated as **hypotenuse divided by the adjacent side** (or **1/cosine**). It’s one of the six primary trigonometric ratios, alongside sine, cosine, tangent, cosecant, and cotangent. Think of it as the “opposite” of cosine: where cosine tells you how much of the hypotenuse aligns ...
