Support latex equations with MathJax

[rcalsaverini]

It shouldn't be difficult to add latex support with MathJax. I think a good chunk of the users would be interested in something like this.

Well, I managed to make it work for me by just adding the following snippet to the file _includes/head/custom.html:

<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { equationNumbers: { autoNumber: "all" } } }); </script>
<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    tex2jax: {
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],
      processEscapes: true
    }
  });
</script>
<script src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML" type="text/javascript"></script>

@rcalsaverini Thanks for the above snippet.

This snippet doesn't work for the display math which starts and ends with $$. Anyone can fix it ?

[rcalsaverini]

Hi @jasonyanglu, the snippet above should work for display math using $$math here$$. I use this in my personal blog, so I know it works there. Can you please check if there are trailing spaces before or after your equation? Maybe this is the problem.

[rcalsaverini]

Ok, I just tested here and my setup works even with trailing spaces. It's probably another problem. Can you check if equations do get rendered if they're enclosed in $...$, \[...\] and \(...\)?

[jasonyanglu]

Hi @rcalsaverini, thanks for you quick response. I tried and found that it works only if the latex content is in the same line with $$ like:

$$z_{1-\alpha/2}\sigma\sqrt{2/n}$$

If it is writen as

$$
z_{1-\alpha/2}\sigma\sqrt{2/n}
$$

Then it does not work. However, there still a problem that the align environment does not work:

$$\begin{aligned}H_0:&\mu_0-\mu_1=0\\H_1:&\mu_0-\mu_1=\delta\end{aligned}$$

Can you help figure it out? Thanks a lot.

MathJax has been bumped to version 3.0 and I've added some notes to the template's guide page since markdown causes some minor issues with it.
