enable for math-environments in LaTeX
It would be really great if it was possible to make this work for some math-environments in LaTeX. For instance \begin{equation} 1+1 \end{equation}, and other environments, like align would really make this a protool.
Thanks, I've been meaning to add this but since I use markdown I haven't got round to it. Will try to get round to it though, PRs also welcome.

It should now work for common math environments - please test with latest version 1.1
This is super useful and seems to be working well in latex documents.
Is it possible to support macros in equation environments? For example, those created with \newcommand?
I have a number of user defined macros for common variables and it would be very useful if they were also rendered in the preview.
Hi @jasonmcewen - it's not possible to use macros at the moment since preview-inline only processes the chunk of LaTeX that's part of the current math block. There does seem to be scope within MathJax to support macros, though I'm not sure how best to make this work in preview: http://docs.mathjax.org/en/latest/tex.html#defining-tex-macros
I would welcome suggestions for a design however - I could imagine for example being able to manually select a region of text containing macros and getting MathJax to process that and remember it when it generates equation previews. However since I don't use LaTeX (I'm writing pandoc-flavour markdown which I fine more elegant) I'm not sure to what extent this makes sense.
The Latex delimiters "\begin{equation}...\end{equation}" work well. Would it be possible to add support for "\[...\]"? Thanks @mangecoeur.
@mangecoeur I also just noticed that environments such as "\begin{align}...\end{align}" are not included.
@44Space I'm not actually super familiar with LaTeX syntax - I would have expected an align environment to be inside an equation environment. They are not included as environments of their own because MathJax expects them to be inside the equation rather than part of the 'surroundings'. If you have more insight into the expected behaviour in LaTeX I would welcome a PR. Will try to explore a bit if I get the time myself.
\begin{align} ... \end{align} is an alternative to \begin{equation} .... \end{equation} . It's more powerful and is included with the amsmath package which easily allows for multiline equations. Can you please enable support for this as well? Thanks.
There is an issue with this that \align environments can also exist inside \equation environments, and it's not simple to support both. As a workaround it should be possible to simply wrap your align with equation.

Hello, I look into this further and found that \begin{equation} \begin{align} f(x) & = x + x \ & = 2x \end{align} \end{equation} gives an error "Package amsmath: Erroneous nesting of equation structures". The inline preview does work with this wrapping trick. Finally, I found that if you highlight all of the equation text, the inline preview does work but does not update constantly (not a live preview).
On the other I checked that \begin{equation} \begin{align} f(x) & = x + x \ & = 2x \end{align} \end{equation} does work in mathjax. This suggests that align command is supported in mathjax.
Interesting, I verified that \begin{align} x + y \end{align} without the line breaks does work in inline preview. Its the command "&" does work.
