TeX and LaTeX Support

The support for TeX and LaTeX in MathJax involves two functions: the first looks for mathematics within your web page (indicated by math delimiters like $$...$$) and marks the mathematics for later processing by MathJax, and the second is what converts the TeX notation into MathJax’s internal format, where one of MathJax’s output processors then displays it in the web page. In MathJax version 2, these were separated into distinct components (the tex2jax preprocessor and the TeX input jax), but in version 3, the tex2jax functions have been folded into the TeX input jax.

The TeX input jax can be configured to look for whatever markers you want to use for your math delimiters. See the TeX configuration options section for details on how to customize the delimiters, and other options for TeX input.

The TeX input processor handles conversion of your mathematical notation into MathJax’s internal format (which is essentially MathML), and so acts as a TeX to MathML converter. The TeX input processor can also be customized through the use of extensions that define additional functionality (see the TeX and LaTeX extensions section).

Note: if you are not familiar with TeX/LaTeX, a good starting point is the LaTeX Wiki book.
