Include required scripts
Load MathJax to render TeX and LaTeX equations. Use jQuery only if you need to refresh math after a dynamic update.
<script type="text/javascript" src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_CHTML"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
Write equations
Inline equations live inside text. Block equations render on their own line.
\\( x = {-b \pm \sqrt{b^2-4ac} \over 2a} \\)$$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$Inline: \\( ... \\)Block: $$ ... $$
Refresh equations
If you inject new math after page load, queue a MathJax render cycle.
<script>
MathJax.Hub.Queue(["Typeset", MathJax.Hub, document.getElementById("math-target")]);
</script>
