MathJax is now enabled for this site. For example, here are the Lorenz's equations:
\begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{aligned}
which is created by
\begin{aligned}
\dot{x} & = \sigma(y-x)\\
\dot{y} & = \rho x - y - xz\\
\dot{z} & = -\beta z + xy
\end{aligned}
To setup MathJaX with Joomla! is easy.
Just add the following lines before the </head> tag in the file index.php in the template directory; save & close, and you have it.
<script> MathJax = { tex: { inlineMath: [['$', '$'], ['\\(', '\\)']] }, svg: { fontCache: 'global' } }; </script> <script type="text/javascript" id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js"> </script>
There are also commercial plug-ins available for Joomla!
