Talk:Trigonometry/For Enthusiasts/Triangles on a Sphere

This page is getting quite long, and will be far longer if we add proofs. Should some or all of it go into Book 2?--Wisden (talk) 17:54, 19 December 2010 (UTC)

The proofs are best/easiest with vector maths, so that is a strong case for this all being in Book 2. I don't see a natural way to split it up, certainly not theorems on one page, proofs on another. I'd suggest we let it grow, and when it is 'too big' we'll have a better idea how to split it. -- JamesCrook (talk) 21:58, 19 December 2010 (UTC)
