   Sin  //  Elementwise sine operation


Description
===========

Produces a tensor of the same element type and shape as ``arg,``
where the value at each coordinate of ``output`` is the sine
of the value at the corresponding coordinate of ``arg.``

Mathematical Definition
=======================

.. math::

   \mathtt{output}_{i_0, \ldots, i_{n-1}} = \sin(\mathtt{arg}_{i_0, \ldots, i_{n-1}})

Backprop
========

.. math::

   \overline{\mathtt{arg}} \leftarrow \Delta\ \cos(\mathtt{arg})
