comment Triangle mapped on a sphere in $\mathbb R^3$?
Shouldn't you at least specify what kind of mapping you want? I won't close it as per @mr.wizard's request, but I was very much tempted to do so. The question doesn't seem to be directly related to Mathematica and requires quite a bit of interpretative effort of the people here. Could have been much better.

Perhaps ConvexHull could do something for you.

This is a site about the language MathematicA. It's not about mathematicS!

comment Solve recursion $a_{n}=ba_{n-1}+cd^{n-1}$
I think you made a mistake somewhere. Mathematica finds me RSolve[{a[n] == b a[n \[Minus] 1] + c d^(n - 1), a[0] == 0}, a[n], n] ==> {{a[n] -> (c (b^n - d^n))/(b - d)}}

comment How do I convert the distance between two lat/long points into feet/meters?
@J.M. It might have been once but it's a built-in function now.
