Reference Entry
Several definitions of the term "secant" are presented. It refers to a straight line or ray that intersects a curve, especially a circle, at two or more points. It also refers to the ratio of the length of the hypotenuse in a right triangle to the side adjacent to an acute angle; the inverse of the cosine.
