[IPython-dev] Using \( \), \[ \] instead of $...$, $$...$$ fox LaTeX math

[Joon Ro]

You are right. Actually, if I change \(  \) to \\(  \\) in a markdown  
cell, it works.

It seems this is caused by markdown parses those things, and regards them  
as its formatting syntax.

It is affecting not only \[  \] stuff but also some other math expressions.
For example, the following does not work:

$$ \underline{x}_{1} x_{2} $$

It works after escaping the first _ with \_:

$$ \underline{x}\_{1} x_{2} $$

I wonder if there is a way to parse math stuff independently from the  
markdown texts.
I found a discussion about this:  
http://doswa.com/2011/07/20/mathjax-in-markdown.html

Thank you,
Joon
