JavaScript Math tan( ) Method

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));

</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 Mathe 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)); 
</script> 

Output:

Result : 1.557407724654902

Program 2: When PI is passed as a parameter.

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

Output:

Result : 0.9999999999999999
