jax.numpy.acos

jax.numpy.acos(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), then x = 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
