Back # Math.sin

The ** Math.sin()** function returns the sine of a number.

`Math.sin(``x`)

`x`

- A number (given in radians).

The `Math.sin()`

method returns a numeric value between -1 and 1, which represents the sine of the angle given in radians.

Because `sin()`

is a static method of `Math`

, you always use it as `Math.sin()`

, rather than as a method of a `Math`

object you created (`Math`

is not a constructor).

`Math.sin()`

Math.sin(0); // 0 Math.sin(1); // 0.8414709848078965 Math.sin(Math.PI / 2); // 1
