Which trigonometric function is defined as the ratio of the hypotenuse to the adjacent side in a right triangle?
Show answer
Secant
The secant function is the reciprocal of the cosine function. In the context of a unit circle, it represents the length of the line segment from the origin to the point where a tangent line at the terminal side intersects the x-axis.
