We use
MathJax to include mathematical formulas in Axional Docs documents. LaTeX
or AsciiMath notation can be used, and the mathematics will be processed
using JavaScript to produce HTML for viewing in any modern browser.
1 Putting mathematics in a document
To put mathematics in your web page, you can use TeX and LaTeX notation, AsciiMath notation, or a combination of all three within the same page.
Mathematics that is written in TeX or LaTeX format is indicated using math delimiters that surround the mathematics, telling MathJax what part of your page represents mathematics and what is normal text.
