In this article, you will learn how to use the Math.sin() method in JavaScript.

## The Math.sin() method

The Math.sin function returns the sine of the angle specified as an argument.

The angle is specified in radians.

The syntax is below.

```
Math.sin(x)
```

x: The angle in radians

If you want to use angles in degrees, you need to convert them to radians.

```
Math.sin(degrees*(Math.PI/180))
```

For example, to get sin30°, sin45°, and sin60°:

```
Math.sin(30*(Math.PI/180));
Math.sin(45*(Math.PI/180));
Math.sin(60*(Math.PI/180));
```
