title: How can I properly format this equation in the title of my plot? (python 3)
body: <p>I am trying to add a title with the correct syntax to print the formula for a Gaussian distribution and don't see my mistake. Can someone help me spot it? My attempt is below and <a href="https://i.imgur.com/6d8weRN.png" rel="nofollow noreferrer">produces this result</a> while the formula should look like f(x) = <a href="https://i.imgur.com/W1kA32n.png" rel="nofollow noreferrer"><em>right hand side of this</em></a>. I am asking for python3, though I think it's the same as LaTeX.</p>
  
  <pre><code>title = "Gaussian Distribution: f(x) = $\\frac{1/\sigma (2\pi)^{frac{1/2}}} \exp( \\frac{(x-\mu)^2 / 2\sigma^2} )"
  plt.title(title)
  </code></pre>
