Python 3 - Number radians() Method

---

Description

The radians() method converts angle x from degrees to radians.

Syntax

Following is the syntax for radians() method −

radians(x)

Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.

Parameters

x − This must be a numeric value.

Return Value

This method returns radian value of an angle.

Example

The following example shows the usage of radians() method.

#!/usr/bin/python3
import math

print ("radians(3) : ",  math.radians(3))
print ("radians(-3) : ",  math.radians(-3))
print ("radians(0) : ",  math.radians(0))
print ("radians(math.pi) : ",  math.radians(math.pi))
print ("radians(math.pi/2) : ",  math.radians(math.pi/2))
print ("radians(math.pi/4) : ",  math.radians(math.pi/4))

Output

When we run the above program, it produces the following result −

radians(3) :  0.0523598775598
radians(-3) :  -0.0523598775598
radians(0) :  0.0
radians(math.pi) :  0.0548311355616
radians(math.pi/2) :  0.0274155677808
radians(math.pi/4) :  0.0137077838904
