## Arctangent definition

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

arctan(y) = tan-1(y) = x+

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°
