mindspore.numpy.arccos
- mindspore.numpy.arccos(x, dtype=None)[source]
Trigonometric inverse cosine, element-wise.
Note
Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported.
- Parameters
x (Tensor) – Input tensor. x-coordinate on the unit circle. For real arguments, the domain is \([-1, 1]\).
dtype (
mindspore.dtype
, optional) – Default:None
. Overrides the dtype of the output Tensor.
- Returns
Tensor.
- Raises
TypeError – If the input is not a tensor.
- Supported Platforms:

Examples
>>> import mindspore.numpy as np >>> x = np.asarray([1, -1], np.float32) >>> output = np.arccos(x) >>> print(output) [0. 3.1415927]
