secant (redirected from secants)

se·cant  (sknt, -knt) n. Abbr. sec 1. a. A straight line intersecting a curve at two or more points. b. The straight line drawn from the center through one end of a circular arc and intersecting the tangent to the other end of the arc. c. The ratio of the length of this line to the length of the radius of the circle. 2. The reciprocal of the cosine of an angle in a right triangle. [From Latin secns, secant-, present participle of secre, to cut; see sek- in Indo-European roots.]

secant  (sknt)

1. A straight line or ray that intersects a curve, especially a circle, at two or more points.

2. The ratio of the length of the hypotenuse in a right triangle to the side adjacent to an acute angle. The secant is the inverse of the cosine.

3. The reciprocal of the abscissa of the endpoint of an arc of a unit circle centered at the origin of a Cartesian coordinate system, the arc being of length x and measured counterclockwise from the point (1, 0) if x is positive or clockwise if x is negative.

4. A function of a number x, equal to the secant of an angle whose measure in radians is equal to x.
