JavaScript Math sin( ) Method

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

  • Example:
    filter_none

    edit
    close

    play_arrow

    link
    brightness_4
    code

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

    chevron_right

    
    

  • 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.

code

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

Output:

Result : 0.8414709848078965

Program 2: When PI is passed as a parameter.
