Definitions specific to this category can be found in Definitions/Secants.

Secant Function

In the above right triangle, we are concerned about the angle $\theta$.

The secant of $\angle \theta$ is defined as being $\dfrac{\text{Hypotenuse}} {\text{Adjacent}}$.

Secant Line

Let $f: \R \to \R$ be a real function.

Let the graph of $f$ be depicted on a Cartesian plane.

A secant to $f$ is a straight line which intersects the graph of $f$ in (at least) two points.

In the above diagram, the secant is the line $AB$ in $\color { blue } {\text {blue} }$.
