I am using jQmath and its perfectly working in both mobile and desktop for all equations
For displaying a function below with comma separated between a(1-cos2x),b inside table e.g. below:
$f(x) = \{\table a(1-cos2x), \, b; x-c, \, d$
In the above equation displaying of comma (,) is missing even after using escape by \ character.
Anyone facing similar issue?
