Inverse Tangent Calculator

Calculate the inverse tangent of a number

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.
