Parameters

xarray_like

Angle, given in degrees.

outndarray, optional

Returns

scalar or ndarray

Cotangent at the input.

Examples

>>> import scipy.special as sc

It is more accurate than using cotangent directly.

>>> x = 90 + 180 * np.arange(3)
>>> sc.cotdg(x)
array([0., 0., 0.])
>>> 1 / np.tan(x * np.pi / 180)
array([6.1232340e-17, 1.8369702e-16, 3.0616170e-16])
