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 numpy as np >>> 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])
