title: Inline math mode on iPython notebook
body: <p>In iPython notebook, how can I write a mathematic formula such as <code>r^2</code> in a line (inline math mode in latex vocabulary). ie. Is it possible to not go on a new line when the formula is printed.</p>
  
  <p>If like in LaTeX, it should be <code>\(r^2\)</code> but it doesn't work...</p>
  
  <p>Thanks for your help !</p>
