secant,

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

Secant

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.
