Thanks, Frederick, thanks, David.
I'm looking for a formula, for an All-Haversine one, which I enter with the Lat, Dec (or LatDest) and dLon to obtain - in one go, no matter how long or complicated, - the initial azimuth.
I was told there is a formula solver/simplifier - the Sage, but I could not mater using it yet...
As a last resort I plan to express all the haversines as the squared sines of the halved angles, put the HC calculation step - expanded - into the formula for the azimuth instead of every HC instance there.
