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 multiplicative inverse (or reciprocal) trigonometric function of the cosine

How to find the measure of an angle that is inscribed from a secant and tangent line
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 [sin], cosine [cos], tangent [tan], cosecant [csc], and cotangent [cot].)
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'.
The value of the secant function can be determined by taking the ratio of the hypotenuse and base of a right-angled triangle. It is the reciprocal of cosine function.
