old LFAQ less frequently asked questions
Moved here from https://github.com/mathjax/MathJax/wiki/LFAQ----less-frequently-asked-questions
The MathJax FAQ <http://www.mathjax.org/resources/faqs/>_ answers many basic questions about MathJax.
The MathJax User Group <http://groups.google.com/group/mathjax-users/>_ is the right place to ask further questions.
On this page we collect some of useful threads from the Mathjax User Group.
WARNING Use at your own risk!
Some (but not all) solutions below involve hacks and use undocumented features of MathJax. We give no guarantee that such hacks will work in future versions of MathJax. If you're uncertain about this, ask us on the User Group.

Yes, but MathJax performs much of its activity asynchronously so be sure to
synchronize your code with MathJax <http://www.mathjax.org/docs/2.0/synchronize.html>.

Yes, see this thread <https://groups.google.com/forum/#!msg/mathjax-users/unL8IjcrTto/DjHpH4BbPRcJ>_ for an example, but again keep in mind that MathJax performs much its activity asynchronoulsy.
MathJax processes the formulas when the page is loaded but you must ask
MathJax to reprocess the formulas that are modified/created later. See Modifying Math on the Page <http://www.mathjax.org/docs/1.1/typeset.html>_

There aren't many, but here's one discussion <https://groups.google.com/forum/#!msg/mathjax-users/aCj-qkCp3hY/nxd56AUC7coJ>_ .
Examples:
-
\sqrt\frac{3}{4}doesn't work. Enclosing the argument in curly braces works\sqrt{\frac{3}{4}} -
\hat \mathbf uworks in article, not in amsart (or MathJax) --\hat{\mathbf u}works in amsart and MathJax.
Here's a thread discussing it <http://groups.google.com/group/mathjax-users/browse_thread/thread/cd9806f1fd33310e/e4a9dfc673e48264>_ and here's code <https://github.com/ppurka/sagenb/blob/235e4869a8cccebf527306320a3a72ff98f46cab/sagenb/data/sage/js/DoubleClickEvent.js>_ that might help you get started.
See this thread <http://groups.google.com/group/mathjax-users/browse_thread/thread/d80ae6ba62a9ae84/7197bb1868c4ae68>_ but note that there are very few reasons why your browser might fall back to image fonts for rendering -- be sure to check the FAQ <http://www.mathjax.org/resources/faqs/#image-fonts>_
See this thread <https://groups.google.com/forum/#!topic/mathjax-users/_UMt3C7TIpQ/discussion>_ for an example that works in Firefox, Safari and Chrome.
MathJax currently only supports STIX and our own webfonts (which are based on TeX Computer Modern and AMS fonts). For the technical reasons, see this thread <https://groups.google.com/d/msg/mathjax-users/XVrMF_S44UE/wmm5_gil8BwJ>. For unsupported hacks, see this thread <https://groups.google.com/forum/#!topic/mathjax-users/PjcC7lqbNGs/discussion>, and even more information at this tread <https://groups.google.com/d/topic/mathjax-users/LsC-31yuDpg/discussion>_.
From this thread <https://groups.google.com/d/msg/mathjax-users/_vTqHlpRED8/VuglIdf0C0cJ>_ you get
::
<script type="text/x-mathjax-config">
MathJax.Hub.Queue(
["Remove",MathJax.Message],
print
);
</script>
You should probably switch to SVG rendering on your print-page (see the discussion on the thread).
See this thread <https://groups.google.com/d/topic/mathjax-users/9mtaQae1WJg/discussion>_.
MathJax only strives to implement math-mode macros of TeX, not text-mode. But see this thread <https://groups.google.com/d/topic/mathjax-users/Pzq6Sf69IDI/discussion>_ for more information
See `this thread https://groups.google.com/d/msg/mathjax-users/-8FaQfp5Dz8/VX83KTSu-1kJ'_ for further reading material.
See this thread <https://groups.google.com/d/topic/mathjax-users/_HCDxJbCFjc/discussion>_ -- but this won't improve rendering speed.
MathJax waits 15 seconds for resources to load. Often this is caused by an error in custom configurations, see this thread <https://groups.google.com/d/topic/mathjax-users/LFXTIz4RmvA/discussion>_.
