scipy.special.tandg#
- scipy.special.tandg(x, out=None) = <ufunc 'tandg'>#
Tangent of angle x given in degrees.
- Parameters:
- xarray_like
Angle, given in degrees.
- outndarray, optional
Optional output array for the function results.
- Returns:
- scalar or ndarray
Tangent at the input.
Notes
tandg
has experimental support for Python Array API Standard compatible backends in addition to NumPy. Please consider testing these features by setting an environment variableSCIPY_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

Examples
>>> import numpy as np >>> import scipy.special as sc
It is more accurate than using tangent directly.
>>> x = 180 * np.arange(3) >>> sc.tandg(x) array([0., 0., 0.]) >>> np.tan(x * np.pi / 180) array([ 0.0000000e+00, -1.2246468e-16, -2.4492936e-16])
