Problem to solve
----------------

Create an animation similar to
`<http://faculty.washington.edu/rjl/classes/am583s2014/Square.html>`_.

Hints:

* The following matplotlib commands may be useful::

    fill(x,y,'b')   # fill polygon specified by arrays x and y with blue
    axis('scaled')   # scale x and y axes the same way

* Recall that to rotate a point $(x,y)$ through angle $\theta$ you can
  can compute

  :math:`\hat x = \cos(\theta)x + \sin(\theta)y`

  :math:`\hat y = -\sin(\theta)x + \cos(\theta)y`
