docstring: r"""
      Cosine, element-wise.
  
      Parameters
      ----------
      x : _Symbol or scalar
          Angle, in radians (:math:`2 \pi` rad equals 360 degrees).
      out : _Symbol or None
          Dummy parameter to keep the consistency with the ndarray counterpart.
  
      Returns
      -------
      y : _Symbol
          The corresponding cosine values. This is a scalar if x is a scalar.
  
      Notes
      ----
      This function only supports input type of float.
