secant, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is sec A = length of hypotenuse/ length of side adjacent angle A. (The other five trigonometric functions are sine …

By observing the sign and the monotonicity of the functions sine, cosine, cosecant, and secant in the four quadrants, one can show that is the smallest value for which they are periodic (i.e., is the …

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'.

Secant is a term in mathematics derived from the Latin secare ("to cut"). It may refer to: a secant line, in geometry the secant variety, in algebraic geometry secant (trigonometry) (Latin: secans), the …

Jun 7, 2026 · The secant and cosecant of an angle θ are defined as the reciprocals of cos (θ) and sin (θ), extending trigonometric relationships.

Jul 23, 2025 · Secant is one of the six basic trigonometric ratios and its formula is secant (θ) = hypotenuse/base, it is also represented as, sec (θ). It is the inverse (reciprocal) ratio of the cosine …

The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle. It is the reciprocal of cosine function and hence, is …

A tangent line just touches a curve at a point, matching the curve's slope there. (From the Latin tangens "touching", like in the word "tangible".) A secant line intersects two or more points on a curve. (From …

When the length of the hypotenuse is divided by the length of the adjacent side, it gives the secant of the angle, of the right-angled triangle. Secant is denoted as 'sec'.

Secant is the trigonometric function defined as the reciprocal of cosine. Written sec θ, it equals 1/cos θ and is undefined wherever cosine equals zero.
