## Parameters

### x
({{< req >}})
Value to operate on.




## Examples

- [Return the sine and cosine of a value](#return-the-sine-and-cosine-of-a-value)
- [Use math.sincos in map](#use-mathsincos-in-map)

### Return the sine and cosine of a value

```js
import "math"

math.sincos(x: 1.23)// {cos: 0.3342377271245026, sin: 0.9424888019316975}


```


### Use math.sincos in map

```js
import "math"
import "sampledata"

sampledata.float()
    |> map(
        fn: (r) => {
            result = math.sincos(x: r._value)

            return {_time: r._time, tag: r._tag, sin: result.sin, cos: result.cos}
        },
    )

```
