# scipy.special.sindg

scipy.special.sindg(x, out=None) = <ufunc 'sindg'>

  Sine of the angle x given in degrees.

  Parameters:
    x array_like

      Angle, given in degrees.

    out ndarray, optional

      Optional output array for the function results.

  Returns:
    scalar or ndarray

      Sine at the input.

  Notes

  Array API Standard Support

  `sindg` has experimental support for Python Array API Standard compatible backends in addition to NumPy. Please consider testing these features by setting an environment variable `SCIPY_ARRAY_API=1` and providing CuPy, PyTorch, JAX, or Dask arrays as array arguments. The following combinations of backend and device (or other capability) are supported.

  Library | CPU | GPU
  --- | --- | ---
  NumPy | ✅ | n/a
  CuPy | n/a | ✅
  PyTorch | ✅ | ⛔
  JAX | ✅ | ⛔
  Dask | ✅ | n/a

  See Support for the array API standard for more information.

  Examples

      >>> import numpy as np
      >>> import scipy.special as sc

  It is more accurate than using sine directly.

      >>> x = 180 * np.arange(3)
      >>> sc.sindg(x)
      array([ 0., -0.,  0.])
      >>> np.sin(x * np.pi / 180)
      array([ 0.0000000e+00,  1.2246468e-16, -2.4492936e-16])
