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.

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
