- 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'

A secant line intersects two or more points on a curve (From the Latin secare "cut or sever") They are lines, so extend in both directions infinitely Circle On a circle they look like this: Theorems There are three theorems of interest here: Intersecting Secants Theorem Intersecting Chords Theorem Angle of Intersecting Secants Theorem
- 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 Definition Meaning - Merriam-Webster
: a straight line cutting a curve at two or more points : a straight line drawn from the center of a circle through one end of a circular arc to a tangent drawn from the other end of the arc
- 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 line - Wikipedia
In geometry, a secant is a line that intersects a curve at a minimum of two distinct points [1] The word secant comes from the Latin word secare, meaning to cut [2] In the case of a circle, a secant intersects the circle at exactly two points
