JavaScript Math tan( ) Method
Below is the example of the Math tan() Method.
Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!
- Example:
Javascript
<script type="text/javascript"> document.write("When zero is passed as a parameter: " + Math.tan(0));</script> |
Output:
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.
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.
Javascript
<script type="text/javascript"> document.write("Result : " + Math.tan(Math.PI / 4));</script> |
Output:
Result : 0.9999999999999999
