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.
