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].) From the definition of the tangent of angle A, tan A = length of side opposite to angle A/ length of side ...
Trigonometric functions - Wikipedia
The trigonometric functions most commonly used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less commonly used. Each of these six trigonometric functions has a corresponding inverse function and has an analog among the hyperbolic functions. The oldest definitions of ...
Secant function (sec) - Trigonometry - Math Open Reference
Secant (sec) - Trigonometry function (See also Secant of a circle). 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 the secant method, a root-finding algorithm in numerical analysis, based on secant lines to graphs of functions a ...
Secant and Cosecant - Algebrica
The secant and cosecant of an angle θ are defined as the reciprocals of cos(θ) and sin(θ), extending trigonometric relationships.
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. In this article, we have covered, about Scant Formula, related examples and others in detail.
