JavaScript Math tan( ) Method
  • Last Updated : 23 Nov, 2020

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

  • Example: 


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


When  zero is  passed as a parameter: 0

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.



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.  


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


Result : 1.557407724654902

Program 2: When PI is passed as a parameter.  


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


Result : 0.9999999999999999
