The Math.tan() method 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. The 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: This method accept a single parameter as mentioned above and described below:  



  • value which is a number representing an angle in radians.

Returns: The Math.tan() method returns the tangent of the given numbers.

Below example illustrate the Math tan() method in JavaScript: 

  • Example 1: 
Input : Math.tan(0)
Output : 0
  • Example 2: 
Input : Math.tan(1)
Output : 1.557407724654902
  • Example 3: 
Input : Math.tan(Math.PI / 4)
Output : 0.9999999999999999

More codes for the above method are as follows: 

Program 1: When 1 is passed as a parameter.  

Javascript




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

Output: 

Result : 1.557407724654902

Program 2: When PI is passed as a parameter.
