title: polar plot in python
body: <p>I am trying to make a polar plot of <code>1/t</code>.  What I have so far is below (which may be wrong).  How can I finish this or make it work?</p>
  
  <pre><code>from pylab import *
  import matplotlib.pyplot as plt
  
  theta = arange(0, 6 * pi, 0.01)
  
  
  def f(theta):
      return 1 / theta
  </code></pre>
