Fixing MathJax

[Daniel]

I just noticed that MathJax was broken on my tetration website. They have updated their JavaScript to connect with a different service. I replaced the old MathJax JavaScript with the following which fixed inline expressions like \(f(x)\). I apologize if folks already know this.

<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>
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script><script type="text/javascript" id="MathJax-script" async
  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml.js">
</script>
