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 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
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'.
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 formula is derived out from the inverse cosine (cos) ratio.
The secant and cosecant of an angle θ are defined as the reciprocals of cos (θ) and sin (θ), extending trigonometric relationships.

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 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.
