The ** tan()** function returns the tangent of a number in radians.

The mathematical representation of the `tan()`

function is shown below.

Note:

`dart:math`

is required for this function.- The
`tan()`

function only works for right-angled triangles.

```
double tan(double num)
```

This function requires a number, `num`

, that represents an angle in radians.

In order to convert degrees to radians, use the following formula:

```
radians = degrees * ( pi / 180 )
```

`tan()`

returns the tangent of the number that is sent as a parameter.

import 'dart:convert';import 'dart:math';void main() {//positive number in radiansprint("The value of tan(2.3): ${tan(2.3)}");// negative number in radiansprint("The value of tan(-2.3): ${tan(-2.3)}");//converting the degrees angle into radians and then applying tan()// degrees = 45.0// PI = 3.14159265// result first converts degrees to radians then apply tandouble result=tan(45.0 * (pi / 180.0));print("The value of tan(45.0 * (pi / 180.0)): ${result}");}
