```python
tensorplay.functional.asin(input: Tensor, *, out: Tensor | None) → Tensor
```

Returns a new tensor with the arcsine of the elements of input.

$$\text{out}_{i} = \sin^{-1}(\text{input}_{i})$$

Parameters:

input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

Keyword Arguments:

out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), optional) – the output tensor.

Example:

```
>>> a = tensorplay.randn(4)
>>> a
tensor([-0.5962,  1.4985, -0.4396,  1.4525])
>>> tensorplay.asin(a)
tensor([-0.6387,     nan, -0.4552,     nan])
```
