jax.numpy.arccos#
- jax.numpy.arccos(x, /)#
Trigonometric inverse cosine, element-wise.
LAX-backend implementation of
numpy.arccos().Original docstring below.
The inverse of cos so that, if
y = cos(x), thenx = arccos(y).- Parameters
x (array_like) – x-coordinate on the unit circle. For real arguments, the domain is [-1, 1].
- Returns
angle – The angle of the ray intersecting the unit circle at the given x-coordinate in radians [0, pi]. This is a scalar if x is a scalar.
- Return type
ndarray
