Python3.x Python3 atan() Function

Python3 Numbers

Description

atan() returns the arctangent of x in radians.

Syntax

The following is the syntax for the atan() method:

import math
math.atan(x)

Note: atan() is not directly accessible; you need to import the math module and then call the method via the math static object.

Parameters

x -- A numeric value.

Return Value

Returns the arctangent of x in radians.

Example

The following shows an example of using the atan() method:

#!/usr/bin/python3
import math

print ("atan(0.64) : ", math.atan(0.64))
print ("atan(0) : ", math.atan(0))
print ("atan(10) : ", math.atan(10))
print ("atan(-1) : ", math.atan(-1))
print ("atan(1) : ", math.atan(1))

After running the above example, the output result is:

atan(0.64) : 0.5693131911006619
atan(0) : 0.0
atan(10) : 1.4711276743037347
atan(-1) : -0.7853981633974483
atan(1) : 0.7853981633974483
