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

  \(\hat x = \cos(\theta)x + \sin(\theta)y\)

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

There is no quiz for Lab 15
