JavaScript Math cos( ) Method

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

  • Example:
    filter_none

    edit
    close

    play_arrow

    link
    brightness_4
    code

    <script type="text/javascript">
             document.write("The cos of 0 : " + Math.cos(0));
    </script>

    chevron_right

    
    

  • Output:
    The cos of 0 : 1

The Math.cos() method 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. The 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: This function accepts single parameter as mentioned above and described below:

  • value: This parameter is a number given in radians.

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



Below example illustrate the cos() method in JavaScript:

  • Example 1:
    Input: Math.cos(010)
    Output : -0.14550003380861354
  • Example 2:
    Input: Math.cos(10)
    Output : -0.8390715290764524

More codes for the above method are as follows:
Program 1: When 1 is passed as a parameter.

filter_none

edit
close

play_arrow

link
brightness_4
code

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

chevron_right


Output:

Result : 0.5403023058681398

Program 2: When PI is passed as a parameter.

filter_none

link
brightness_4
code

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

chevron_right


Output:

Result : -1
