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