scipy.special.cotdg#
- scipy.special.cotdg(x, out=None) = <ufunc 'cotdg'>#
Cotangent of the 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
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])
