 # Python | PyTorch sin () method

The ` torch.sin () ` function provides support for the sine function in PyTorch. It expects input in radians, and output is in the range [-1, 1]. Input type — tensor, and if the input contains more than one element, the elementwise sine is calculated.

Syntax : torch.sin (x, out = None)

Parameters :
x : Input tensor
name (optional): Output tensor

Return type : A tensor with the same type as that of x.
