Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less used. Each of these six trigonometric functions has a corresponding inverse function, and an analog among the hyperbolic functions.
Learn the definition, formula, graph, and inverse of the secant function, one of the six trigonometric functions. Find out how to use secant in calculus, angles, and problems.
Secant is a term in mathematics derived from the Latin secare ("to cut"). It may refer to a secant line, a secant variety, a secant function, a secant method, or a secant ogive.
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].)
In trigonometry, the secant is a function that associates an angle α with the reciprocal of the cosine. It is denoted as sec and is expressed as: $$ \sec \alpha = \frac {1} {\cos \alpha} $$. 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.
A secant line is a line that intersects a curve or a set of points at least twice. Learn about the properties, definitions, and applications of secant lines in geometry, calculus, and discrete mathematics.
