cmath.atan() function calculates the arc tangent of a given complex number. The input value can be a real or complex number but the returned value will always be complex.
math.atan(x)x |
The value(real or complex) whose inverse tangent is to be calculated |
The function returns the arc tangent of the given number ,x, in radians. The returned value is a complex number iregardless of whether the input value is real or complex. If x is a real number, the returned value has 0j as its complex number.
