Secant Calculator

The Secant calculator helps you calculate the secant of an angle. You can switch between degrees and radians.

Simply enter the value of Angle α and choose between degrees and radians to find the sec(α).

Secant is the ratio of the hypotenuse to the shorter side adjacent to an acute angle in a right-angled triangle in trigonometry. Secant is cosine’s reciprocal.

The secant formula is:

sec(α) =hypotenuse/adjacent=c/b
