Python | math.sin () function

In Python, a math module contains a number of math operations that can be easily accomplished using the module. math.sin() returns the sine of the value passed as an argument. The value passed to this function must be in radians.

Syntax: math.sin (x)

Parameter:
x: value to be passed to sin ()

Returns: Returns the sine of value passed as argument

Code # 1:

# Python code to demonstrate how sin () works   # import & quot; math & quot; for math operations import math    a = math.pi / 6   # returns sine pi / 6 print ( "The value of sine of pi / 6 is:" , end = "")  print (math.sin (a))

Output:

 The value of sine of pi / 6 is: 0.49999999999999994
