## Arctangent definition

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

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

As we all know that 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°
