## Integrating MathJax

A feature commonly requested by markers was the ability to annotate student submissions with LaTeX like math. This has now been implemented!

Anywhere annotations exist markers can enter LaTeX like math thanks to MathJax. When creating an annotation the marker just needs to surround the math in a pair of dollar-sign symbols. The entire annotation shown in the image above is:

should actually be $$\lt \frac 1 2$$

As would be expected, students also see LaTeX like math when viewing an annotation with math in it. This math rendering system expands (and reinforces) the utility of Markus for theory-based courses such as calculus, discrete math or linear algebra.

In addition to the MathJax integration, markers can now preview their annotation prior to submitting it.

The preview functionality will help speedup the marking process for users unfamiliar with MathJax syntax. Instead of submitting an annotation, hovering over it and then editing it, markers can now preview exactly how their annotation will look once submitted. This also allows markers to preview rich HTML annotations with bolded and italicized text.
