The JavaScript 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 between 1 and -1. 

Example 1: Below is an example of the Math sin() Method.

JavaScript
console.log("When zero is passed as a parameter: "
    + Math.sin(0));

Output
When zero is passed as a parameter: 0

Example 2: When 1 is passed as a parameter. 

JavaScript
console.log("Result : " + Math.sin(1));

Output
Result : 0.8414709848078965
