Python 3 - Number sin() Method


Advertisements

Description

The sin() method returns the sine of x, in radians.

Syntax

Following is the syntax for sin() method −

sin(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 a numeric value between -1 and 1, which represents the sine of the parameter x.

Example

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

#!/usr/bin/python3
import math

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

Output

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

sin(3) :  0.14112000806
sin(-3) :  -0.14112000806
sin(0) :  0.0
sin(math.pi) :  1.22460635382e-16
sin(math.pi/2) :  1
