code: def sin(x, out=None, where=None, **kwargs):
      r"""
      Trigonometric sine, element-wise.
  
      Parameters
      ----------
      x : array_like
          Angle, in radians (:math:`2 \pi` rad equals 360 degrees).
      out : Tensor, None, or tuple of Tensor and None, optional
          A location into which the result is stored. If provided, it must have
          a shape that the inputs broadcast to. If not provided or `None`,
          a freshly-allocated tensor is returned. A tuple (possible only as a
          keyword argument) must have length equal to the number of outputs.
      where : array_like, optional
          Values of True indicate to calculate the ufunc at that position, values
          of False indicate to leave the value in the output alone.
      **kwargs
  
      Returns
      -------
      y : array_like
          The sine of each element of x.

      --------
      arcsin, sinh, cos
  
      Notes
      -----
      The sine is one of the fundamental functions of trigonometry (the
      mathematical study of triangles).  Consider a circle of radius 1
      centered on the origin.  A ray comes in from the :math:`+x` axis, makes
      an angle at the origin (measured counter-clockwise from that axis), and
      departs from the origin.  The :math:`y` coordinate of the outgoing
      ray's intersection with the unit circle is the sine of that angle.  It
      ranges from -1 for :math:`x=3\pi / 2` to +1 for :math:`\pi / 2.`  The
      function has zeroes where the angle is a multiple of :math:`\pi`.
      Sines of angles between :math:`\pi` and :math:`2\pi` are negative.
      The numerous properties of the sine and related functions are included
      in any standard trigonometry text.
  
      Examples
      --------
      Print sine of one angle:
  
      >>> import mars.tensor as mt
  
      >>> mt.sin(mt.pi/2.).execute()
      1.0
  
      Print sines of an array of angles given in degrees:
  
      >>> mt.sin(mt.array((0., 30., 45., 60., 90.)) * mt.pi / 180. ).execute()
      array([ 0.        ,  0.5       ,  0.70710678,  0.8660254 ,  1.        ])
  
      Plot the sine function:
  
      >>> import matplotlib.pylab as plt
      >>> x = mt.linspace(-mt.pi, mt.pi, 201)
      >>> plt.plot(x.execute(), mt.sin(x).execute())
      >>> plt.xlabel('Angle [rad]')
      >>> plt.ylabel('sin(x)')
      >>> plt.axis('tight')
      >>> plt.show()
