How do I prevent Org Mode from including MathJax when exporting as html?
You can set the mathjax HTML template to be blank:
(setf org-html-mathjax-template "")
This should stop org from exporting any mathjax stuff at all.
The documentation says:
If you prefer, you can also request that LaTeX fragments are processed into small images that will be inserted into the browser page. Before the availability of MathJax, this was the default method for Org files. This method requires that the ‘dvipng’ program, ‘dvisvgm’ or ‘imagemagick’ suite is available on your system. You can still get this processing with #+OPTIONS: tex:dvipng #+OPTIONS: tex:dvisvgm or: #+OPTIONS: tex:imagemagick
