scipp.sin

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

Element-wise sine.

The input must have a plane-angle unit, i.e. rad, deg.

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 sine values of the input.

Examples

Compute sine of angles in radians:

>>> import scipp as sc
>>> import numpy as np
>>> angle = sc.array(dims=['x'], values=[0.0, np.pi/6, np.pi/4, np.pi/3, np.pi/2], unit='rad')
>>> sc.sin(angle)
<scipp.Variable> (x: 5)    float64  [dimensionless]  [0, 0.5, ..., 0.866025, 1]

The input must have angle units (rad or deg):

>>> angle_deg = sc.array(dims=['x'], values=[0.0, 30.0, 45.0, 60.0, 90.0], unit='deg')
>>> sc.sin(angle_deg)
<scipp.Variable> (x: 5)    float64  [dimensionless]  [0, 0.5, ..., 0.866025, 1]
