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
