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 …

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'.
