[LON-CAPA-admin] [External] tex rendering problem?

[Raeburn, Stuart]

Nathan,

LON-CAPA 2.11.3 and later include a Domain configuration to set the default math render in your LON-CAPA domain.  Unless a Domain Coordinator has set a configuration, it will currently be tth.  To change it, select your Domain Coordinator role and use:

Main Menu > Set domain configuration > Display (Course/Community defaults checked)

Then in the "Defaults which can be overridden in each course by a CC" for this item:
Default method to display mathematics, select MathJax
and push "Save Changes"

Nathan,

The text the student is seeing is from the tth (TeX to HTML) processor.

There are three options for display right now:
MathJax, Convert to Images (mimetex: converts latex to a graphic and displays the graphic) or TeX to HTML.

On a course basis under Course Settings -> Display of Resources you can force the math rendering
engine to one of those three choices or “None Specified - Use Student Choice”.

A student (or other user) can select the math rendering type under their own user preferences. The
default may still be tth.

Under your course settings you can change this to MathJax. My impression is that is now pretty safe,
but the mathematicians may be able to chime in better. This will guaranteed MathJax is used.

(Renderers can be forced in the problem code, but I remember that being frowned upon.)

Hope this helps,
Mark
