Online arctan(x) calculator. Inverse tangent calculator.

The arctangent function is the inverse function of y = tan(x).

arctan(*y*) = tan^{-1}(*y*) = *x*+ *kπ*

For every

*k *= {...,-2,-1,0,1,2,...}

For example, If the tangent of 45° is 1:

tan(45°) = 1

Then the arctangent of 1 is 45°:

arctan(1) = tan^{-1}(1) = 45°
