Inverse Tangent Calculator

The calculator will find the inverse tangent of the given value in radians and degrees.

The inverse tangent $$$y=\tan^{-1}(x)$$$ or $$$y=\operatorname{atan}(x)$$$ or $$$y=\operatorname{arctan}(x)$$$ is such a function that $$$\tan(y)=x$$$.

The domain of the inverse tangent is $$$(-\infty,\infty)$$$, the range is $$$\left(-\frac{\pi}{2},\frac{\pi}{2}\right)$$$.

It is an odd function.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your Input

Find $$$\operatorname{atan}{\left(\sqrt{3} \right)}$$$.

Answer
