scipy.special.cosdg — SciPy v1.15.2 Manual (original) (raw)

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

Cosine 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

Cosine of the input.

Examples

import numpy as np import scipy.special as sc

It is more accurate than using cosine directly.

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