# Python math.sin() – Sine Function

Contents

## Python math.sin()

math.sin(x) function returns the sine of x radians.

The return value lies in [-1, 1].

### Syntax

The syntax to call sin() function is

``math.sin(x)``

where

### Examples

In the following example, we find the sine of 0.5 radians using sin() function of math module.

Python Program

``````import math

result = math.sin(x)
print('sin(x) :', result)``````
Run Code Copy

Output

``sin(x) : 0.479425538604203``

We can take angle in degrees and convert the degrees into radians using math.radians() function, and then find the sine of this angle.

In the following program, we find the sine of 30 degrees.

Python Program

``````import math

x = 30 #degrees
result = math.sin(x)
print('sin(x) :', result)``````
Run Code Copy

Output

``sin(x) : 0.49999999999999994``

### Summary

In this Python Examples tutorial, we learned the syntax of, and examples for math.sin() function.
