In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec (θ) = hypotenuse / adjacent. It is not …

Describes the secant function, which gives the quotient of two sides (hypotenuse over adjacent) for any angle in a right triangle.

We have defined secant, cosecant, and cotangent, as the reciprocal ratios of cosine, sine, and tangent.

The circle definition, a generalization of SOHCAHTOA, is shown below on the right. f (x) = sec x is a periodic function with period 2π.

Secant is a trigonometric function defined as the reciprocal of the cosine function. In a right triangle, the secant of an angle is the ratio of the length of the hypotenuse to the length of the …
