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. 



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. 

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

Example 1: 


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


When zero is passed as a parameter: 0

Example 2: When 1 is passed as a parameter. 


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


Result : 0.8414709848078965

Example 3: When PI is passed as a parameter. 


console.log("Result : " + Math.sin(Math.PI / 2));


Result : 1
