# JavaScript Math sin( ) Method

• Last Updated : 09 Feb, 2022

Below is the example of the Math sin() Method.

• Example:

 `<``script` `type``=``"text/javascript"``> ` `      ``document.write("When zero is  passed as a parameter: "  ` `                     ``+ Math.sin(0)); ` ` `

• Output:
`When zero is  passed as a parameter: 0`

The Math.sin() method in Javascript is used to return the sine of a number. The Math.sin() method returns a numeric value between -1 and 1, which represents the sine of the angle given in radians.

The sin() is a static method of Math, therefore, it is always used as Math.sin(), rather than as a method of a Math object created.

Syntax:

`Math.sin(value)`

Parameters: This method accepts a single parameter as mentioned above and described below:
value which is a number given in radians.

Return Value: The Math.sin() method returns the sine of the given numbers.

Below examples illustrates the Math sin() method in JavaScript:

• Example 1:
```Input : Math.sin(0)
Output : 0```
• Example 1:
```Input : Math.sin(1)
Output : 0.8414709848078965```
• Example 1:
```Input : Math.sin(Math.PI / 2)
Output : 1```

More codes for the above method are as follows:
Program 1: When 1 is passed as a parameter.

 `<``script` `type``=``"text/javascript"``> ` `         ``document.write("Result : " + Math.sin(1)); ` ` `

Output:

`Result : 0.8414709848078965`

Program 2: When PI is passed as a parameter.

 `<``script` `type``=``"text/javascript"``> ` `         ``document.write("Result : " + Math.sin(Math.PI / 2)); ` ` `

Output:

`Result : 1`
