Can you tell the owner to implement LaTex in the site?? Plz. LaTeX is a special type of Markup language that could be incorporated into javascript(by importing a library/package).
It really makes displaying equations easier so let's say I want to write the vis-viva equation to calculate required dV to transfer orbits,
ΔV=√GM[(2/r)-(1/a)]
LaTeX source code:
\Delta V = \sqrt{\mu \cdot (\frac{2}{r}-\frac{1}{a})}
Outputs:

Usually if the site doesn't support LaTeX, use Mathjax. Please look into this, it really makes ΔV calculations and Kepler's laws seem way neater.
