torch.asin
torch.asin(input, *, out=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) -- the input tensor.
Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> a = torch.randn(4)
  >>> a
  tensor([-0.5962,  1.4985, -0.4396,  1.4525])
  >>> torch.asin(a)
  tensor([-0.6387,     nan, -0.4552,     nan])
