class brainunit.math.arccos(x, unit_to_scale=None, **kwargs)#

Inverse cosine, element-wise.

Parameters:

  • x (Array | ndarray | bool | number | bool | int | float | complex | saiunit.Quantity) – Input values in the range [-1, 1].

  • unit_to_scale (saiunit.Unit | None) – Unit used to convert x to a dimensionless number first.

Returns:

out – Angle in radians, in [0, pi].

Return type:

Array

Examples

>>> import saiunit as u
>>> import jax.numpy as jnp
>>> u.math.arccos(jnp.array([1.0, 0.0, -1.0]))
