jax.numpy.arccos

jax.numpy.arccos(x)

Trigonometric inverse cosine, element-wise.

LAX-backend implementation of 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
