jax.numpy.arcsin#
- jax.numpy.arcsin(x, /)[source]#
Compute element-wise inverse of trigonometric sine of input.
JAX implementation of
numpy.arcsin
.- Parameters:
x (ArrayLike) – input array or scalar.
- Returns:
An array containing the inverse trigonometric sine of each element of
x
in radians in the range[-pi/2, pi/2]
, promoting to inexact dtype.- Return type:
Note
jnp.arcsin
returnsnan
whenx
is real-valued and not in the closed interval[-1, 1]
.jnp.arcsin
follows the branch cut convention ofnumpy.arcsin
for complex inputs.

Examples
>>> x = jnp.array([-2, -1, -0.5, 0, 0.5, 1, 2]) >>> with jnp.printoptions(precision=3, suppress=True): ... jnp.arcsin(x) Array([ nan, -1.571, -0.524, 0. , 0.524, 1.571, nan], dtype=float32)
For complex-valued inputs:
>>> with jnp.printoptions(precision=3, suppress=True): ... jnp.arcsin(3+4j) Array(0.634+2.306j, dtype=complex64, weak_type=True)
