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 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 (function) Definition (Illustrated Mathematics Dictionary)
In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec (θ) = hypotenuse / adjacent. It is not commonly used, and is equal to 1/cosine.
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.
Secant and Cosecant - Algebrica
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).
Secant: Introduction to the Secant Function - Wolfram
As the ratio of one and the cosine function that is a particular case of the generalized hypergeometric, Bessel, Struve, and Mathieu functions, the secant function can also be represented as ratios of one and those special functions.
Secant - Math.net
A secant is a line that intersects a curve at a minimum of two different points. The secant line above cuts (intersects) the curve at three distinct points. In Geometry, secant lines are often used in the context of circles. The secant line below, in red, intersects the circle with center O, twice.
