(x: float) => {sin: float, cos: float}

{{% caption %}} For more information, see Function type signatures. {{% /caption %}}

Parameters

x

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

Examples

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}
        },
    )
