`sin()`

function in DartThe ** sin() function** in Dart returns the sine of a number. To be more specific,

`sin()`

returns the sine of a number in radians.The illustration below shows the mathematical representation of the `sin()`

function.

`dart:math`

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

function only works for right-angled triangles.

```
double sin(double num)
```

This function requires a number that represents an angle (in radians) as the parameter. In order to convert degrees to radians, use the following formula:

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

`sin()`

returns the sine of the number (in radians) that is sent as a parameter.

import 'dart:convert';import 'dart:math';void main() {//positive number in radiansprint("The value of sin(2.3): ${sin(2.3)}");// negative number in radiansprint("The value of sin(-2.3): ${sin(-2.3)}");//converting the degrees angle into radians and then applying sin()// degrees = 90.0// PI = 3.14159265// result first converts degrees to radians then apply sindouble result=sin(90.0 * (pi / 180.0));print("The value of sin(90.0 * (pi / 180.0)): ${result}");}
