# scipy.special.cotdg

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

  Cotangent 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

      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])
