Inverse Secant Calculator
Calculate the inverse secant of a number
The calculator will find the inverse secant of the given value in radians and degrees.
The inverse secant $$$y=\sec^{-1}(x)$$$ or $$$y=\operatorname{asec}(x)$$$ or $$$y=\operatorname{arcsec}(x)$$$ is such a function that $$$\sec(y)=x$$$.
The domain of the inverse secant is $$$(-\infty,-1]\cup[1,\infty)$$$, the range is $$$\left[0,\frac{\pi}{2}\right)\cup\left(\frac{\pi}{2},\pi\right]$$$.
This function is neither even nor odd.
