Maths & notation
Render equations with MathJax, from inline fragments to display-mode series expansions.
Published Jul 18, 2026
Technical writing often needs precise notation. MathJax turns TeX-like markup into readable equations without leaving Markdown.
Display math¶
Go to documentation
\[
\cos x=\sum_{k=0}^{\infty}\frac{(-1)^k}{(2k)!}x^{2k}
\]
Configuration note¶
Needs configuration
MathJax is included via a script tag on this page and is not
configured globally by default, so pages without maths stay light.
See the documentation if your whole site is maths-heavy.
