Math.cos( ) In JavaScript

The Math.con() function in Javascript is used to return the cosine of a number.
The Math.cos() method returns a numeric value between -1 and 1, which represents the cosine of the angle given in radians.
cos() is a static method of Math, therefore, it is always used as Math.cos(), rather than as a method of a Math object created.

Syntax:

Math.cos(value)

Parameters Used:
Value:A number given in radians.

Return Value:
The Math.cos() function returns the cosine of the given numbers which range from -1 to 1.

Examples:



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

    Output:

    Output : 1
  2. When 1 is passed as a parameter.
    <script type="text/javascript">
       document.write("Output : " + Math.cos(1));
    </script>

    Output:

    Output : 0.5403023058681398
  3. When PI is passed as a parameter.
    <script type="text/javascript">
       document.write("Output : " + Math.cos(Math.PI));
    </script>

    Output:

    Output : -1
