Formulae
I've deleted a couple of passages that rely on unexplained mathematical formulae (checking the citations doesn't help explain the formulae). These formulae seem to depend on markup notation of the form &lt;math&gt;...&lt;/math&gt;, which is probably supposed to render using mathematical symbols, but doesn't work, at least not in Firefox.

It seems these formulae have existed in this article since it was created - apparently copied here from another article. It may be that they made more sense in that previous article.

I haven't removed all examples of this notation; I've only removed the instances where some or all of the variables are entirely unexplained, rendering the formulae impenetrable. MrDemeanour (talk) 07:57, 2 May 2023 (UTC)
