- 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 Line -- from Wolfram MathWorld
A secant line, also simply called a secant, is a line passing through two points of a curve As the two points are brought together (or, more precisely, as one is brought towards the other), the secant line tends to a tangent line
- 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

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
- 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
