The inverse secant calculator referred to as a arcsec calculator, provides an easy-to-use interface for calculating arcsec values from a given ratio and includes a visual representation of the arcsec function and arcsec graph. Arcsec function also known as inverse secant function, or sec⁻¹ function, returns the value of angle for which sec function is equal to the ratio of the hypotenuse to the side adjacent to an angle in a right triangle. The inverse secant calculator computes arcsec values effortlessly, whether for education, meteorology, computer graphics or also in astronomy.
