So mathematical gentlemen and ladies.
Do the Haversines have it or not? You tell the rest of us simple souls. I'll take your word for it.
I've been happy with Versines for years, but now like the Haversine Doniol as per Greg and Hanno.
In my opinion , the best long hand method for Hc and I intend to trial for TS asap.
