I decided to ask my daughter who will soon be teaching High School Physics...
I will attach a complete TeX or LaTeX equation below. LaTeX is an macro
extension to TeX that eventually converts into TeX before being rendered on a
page. Note also that Microsoft Word has a plugin that helps with equation
editing.
\begin{equation}
\frac{1}{2}k<x^2> = \frac{1}{2} k_B T
\end{equation}
Equipartition theory
Also note that Macintosh OS 10.9 claims to have support for MathML but I
believe there were some grumblings about the support being there but not really
there. This might be like how Mac OS had UI programming available a version
before VoiceOver came out, and if you tried really hard you could have written
a screen reader for that OS. So what I am trying to say is that perhaps in the
current version there is a framework but that true support in applications
will not be available for a couple of years.
Hope my ramblings give you some direction in solving your issues.
Jonathan
Best wishes,
Jonathan
