MathJax, MathML, and LaTex

懷念LaTex ? 或者揮不去的夢魘?

MathJax 讓使用者能夠在Html頁面中以LaTex語法加入方程式,
它也支援 MathML 語法.

得先引用 MathJax的javascript library,


0. config to set  in-line delimiter to $\$$

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({tex2jax: {inlineMath: [['$\$$','$\$$'], ['\\(','\\)']]}});
</script>

1. 透過 http
<script type="text/javascript"
  src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>

2. 或者透過https

<script type="text/javascript"
  src="https://d3eoax9i5htok0.cloudfront.net/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>

當 $a \ne 0$, 方程式 \(ax^2 + bx + c = 0\) 有兩個解 :
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

//=== Production and Staging deploy

• Staging Deployment : http://<guid>.cloudapp.net
  where <guid> is a GUID automatically provided by Windows Azure and the GUID will change each time the application is deleted and re-deployed.
• Production Deployment : http://<urlprefix>.cloudapp.net
  where <urlprefix> is the unique URL prefix specified when creating the hosted service.
