cMath module contains a number of functions which is used for mathematical operations for complex numbers. The cmath.atan() function returns the arctangent value of a complex number. The value passed in this function can be int, float, and complex numbers.
Syntax: cmath.atan(x)
Parameter:This method accepts only single parameters.
- x :This parameter is the value to be passed to atan()
Returns:This function returns the arctangent value of a complex number.
Below examples illustrate the use of above function:
Example #1 : In this example we can see that by using cmath.atan() method, we are able to get the values of arctangent by passing any value to it.
Python3
import cmath
val = cmath.atan( 3 )
print (val)
|
Output:
(1.2490457723982544+0j)
Example 2:
Python3
import cmath
val = cmath.atan( 2 + 5j )
print (val)
|
Output:
(1.4998477994928145+0.17328679513998632j)
