EdX does not support this problem type.
This problem type is a prototype, and is not supported. By default, the ability to create these problems is not enabled in Studio. You must change the advanced settings in your course before you can create problems with LaTeX. Use this problem type with caution.
If you have an problem that is already written in LaTeX, you can use this problem type to easily convert your code into XML. After you paste your code into the LaTeX editor, you make a few adjustments.
If you want to use LaTeX to typeset mathematical expressions in problems that you haven’t yet written, use any of the other problem templates together with MathJax. For more information about how to create mathematical expressions in Studio using MathJax, see Using MathJax for Mathematics.
