sin¶
Trigonometric sine, element-wise.
param x: | (array_like) Angle, in radians (\(2\pi\) rad equals 360 degrees). |
---|---|
returns: | (array_like) The sine of each element of x. |
Example¶
>>> import gumath as gm
>>> from xnd import xnd
>>> x = [0.0, 45 * 3.14159/180, 90 * 3.14159/180]
>>> gm.sin(xnd(x))
xnd([0.0, 0.70710, 0.99999], type='3 * float64')
cos¶
Trigonometric cosine, element-wise.
param x: | (array_like) Angle, in radians (2*pi rad equals 360 degrees). |
---|---|
returns: | (array_like) The cosine of each element of x. |
Example¶
>>> import gumath as gm
>>> from xnd import xnd
>>> x = [0.0, 45 * 3.14159/180, 90 * 3.14159/180]
>>> gm.cos(xnd(x))
xnd([1.0, 0.70710, 6.12323e-17], type='3 * float64')
