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.

Your Input

Find $$$\operatorname{asec}{\left(\sqrt{2} \right)}$$$.


$$$\operatorname{asec}{\left(\sqrt{2} \right)} = \frac{\pi}{4}\approx 0.785398163397448$$$A

$$$\operatorname{asec}{\left(\sqrt{2} \right)} = 45^{\circ}$$$A
