scipp.asin

scipp.asin(x, *, out=None)

Element-wise inverse sine.

The input must be dimensionless and in the range [-1, 1].

Parameters:

• x (scipp.typing.VariableLike) – Input data.

• out (Optional[TypeVar(VariableLikeType, Variable, DataArray, Dataset, DataGroup[Any])], default: None) – Optional output buffer.

Returns:

Same type as input – The inverse sine values of the input in radians.

Examples

Compute the inverse sine:

>>> import scipp as sc
>>> x = sc.array(dims=['x'], values=[0.0, 0.5, 1.0])
>>> sc.asin(x)
<scipp.Variable> (x: 3)    float64            [rad]  [0, 0.523599, 1.5708]

The output is in radians:

>>> sc.asin(sc.scalar(0.5)).to(unit='deg')
<scipp.Variable> ()    float64            [deg]  30
