Math.tan( ) In JavaScript

The Math.tan() function in Javascript is used to return the tangent of a number.
The Math.tan() method returns a numeric value that represents the tangent of the angle.
tan() is a static method of Math, therefore, it is always used as Math.tan(), rather than as a method of a Math object created.

Syntax:

Math.tan(value)

Parameters Used:
Value:A number representing an angle in radians.

Return Value:
The Math.tan() function returns the tangent of the given numbers.

Examples:

Input : Math.tan(0)
Output : 0
     
Input : Math.tan(1)
Output : 1.557407724654902

Input : Math.tan(Math.PI / 4)
Output : 0.9999999999999999

1. When zero is passed as a parameter.

   <script type="text/javascript">    document.write("Output : " + Math.tan(0)); </script>

   Output:

   Output : 0

2. When 1 is passed as a parameter.

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

   Output:

   Output : 1.557407724654902

3. When PI is passed as a parameter.

   <script type="text/javascript">    document.write("Output : " + Math.tan(Math.PI / 4)); </script>

   Output:

   Output : 0.9999999999999999
