How to Find the Angle of Secant?

In trigonometry, secant is a trigonometric function, that can be defined as the ratio of the length of the hypotenuse by the length of the adjacent side. In short form secant can be used as "sec". 


Sec(A) = hypotenuse(c) / adjacent (b)

Secant Formula

Sec(x) = 1/cos(x) = cos(x)-1

y= cos(x)-1

Secant Graph

In the secant function graph, we have repeating curves for every possible angle. Secant is smaller than or = -1 and larger than or =1.
