Related to secant: cosecant


in mathematics. 1 In geometry, a secant is a straight line cutting a curve or surface. If it intersects the curve in two different points, as in the secant of a circlecircle,
closed plane curve consisting of all points at a given distance from some fixed point, called the center. A circle is a conic section cut by a plane perpendicular to the axis of the cone.

, the segment of the secant between the points is called a chord. The limiting position of a secant, if such a limit exists, is called the tangenttangent,
in mathematics. 1 In geometry, the tangent to a circle or sphere is a straight line that intersects the circle or sphere in one and only one point. For other curves and surfaces the tangent line at a given point P

a trigonometric function. In a right triangle, the secant of an acute angle is defined as the ratio of the hypotenuse to the leg adjacent to the angle. The secant is denoted by sec.


The function given by the reciprocal of the cosine function. Abreviated sec.
The secant of an angle A is 1/cos A.
