Python cmath.atan() Method

❮ cmath Methods

Example

Find the arctangent of a complex number:

#import cmath for complex number operations
import cmath

#find the arc tangent of a complex number
print (cmath.atan(2 + 3j))
Try it Yourself »

Definition and Usage

The cmath.atan() method returns the arc tangent of a complex number.

There are mainly two branch cuts:

  1. Extending from 1j along the imaginary axis to ∞j towards the right
  2. Extending from -1j along the imaginary axis to -∞j towards left

Syntax

cmath.atan(x)

Parameter Values

Parameter Description
x Required. A number to find the arctangent of

Technical Details

Return Value: A complex value, representing arc tangent of a complex number
Python Version: 2.6
