title: Sympy in iPython notebook: printing an entire function
body: <p>Currently when printing equations in SymPy it just prints the 'right hand side' of the equation, and does not include the 'left hand side'. E.g.</p>
  
  <pre><code>&gt;&gt;&gt; a = b*d
  &gt;&gt;&gt; a
  b*d 
  </code></pre>
  
  <p>Whereas what I would like is:</p>
  
  <pre><code>&gt;&gt;&gt; a = b*d
  &gt;&gt;&gt; a
  a = b*d
  </code></pre>
  
  <p>For which a big part of this is the nice formatting that mathjax gives, and a bit more readability when I'm showing to colleagues who aren't programmers. Is there a way of including the subject of the equation in the output?</p>
  
  <p>N.B. Apologies, my math terminology is not great</p>
