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 | 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 line - Wikipedia
In geometry, a secant is a line that intersects a curve at a minimum of two distinct points. [1] The word secant comes from the Latin word secare, meaning to cut. [2] In the case of a circle, a secant intersects the circle at exactly two points.
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'. Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used.

The secant function is the reciprocal of the cosine function, thus, the secant function goes to infinity whenever the cosine function is equal to zero (0). The secant formula along with solved examples is explained below.
Secant in Trigonometry Explained Simply - Andrea Minini
Geometrically, the secant (OB) is the point where the line (r), which is tangent at point P on the unit circle, intersects the x-axis. The secant can also be seen as the line segment OC that starts at the origin O, passes through point P, and intersects the tangent at point C.
