# [IPython-dev] mathjax not rendering in notebook

Hi,

I've run into some puzzling trouble using mathjax in the notebook.

Here's some mathjax markdown text:

$$\begin{array}{c} y_1 \cr y_2 \mathtt{t}_i \cr y_{3} \end{array}$$

In the notebook this renders as "$$\begin{array}{c} y_{11} \cr y_{12} \mathtt{t}i \cr y{13} \end{array}$$" - i.e. somehow rejected by
mathjax.   The following make it render correctly:

2) removing _i of \mathtt{t}_i

The same text in an html page works OK:

<!DOCTYPE html>
<html>
<script type="text/javascript"
src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"
charset="utf-8"></script>
<body>
$$\begin{array}{c} y_1 \cr y_2 \mathtt{t}_i \cr y_{3} \end{array}$$
</body>
</html>

I also found that I could not use \\ in the notebook markdown for
newline and had to use \cr.  Again, this was fine in the raw html
mathjax.  Is there anything I can do to debug?

Cheers,

Matthew
