Next message: Federico Rossi: "Re: Spherical Trigonometry"
I would start with Chapter 21 of Bowditch, "Navigational Mathematics."
All the basic relationships are covered, starting from the basic
definitions of geometry, working through plane trigonometry, and ending
with spherical trig. There's not much else needed for modern sight
reductions.
Now, as to "haversines" and so on, I don't know of a text. Maybe
someone else could help.
