JavaScript Math sin( ) Method

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));
  </script>
• 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));
</script>

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));
</script>

Output:

Result : 1
