comment Trilateration on a Sphere given 2 points and 3 distances
When I solve the puzzle, I should have the answer to within a foot of the cache location, if I use the same spherical earth model used to create the puzzle. The location could be anywhere in a 20 mile radius though, which means taking a short cut with the geometry could send me bushwhacking in the wrong place forever. Solving this will require several nights of writing brute-force problem solving algorithms, so I feel like should get the basic calculations right if I'm going to go through all that trouble.

That won't work... this is part of a puzzle that will involve a recursive algorithm that will have to run this calculation several million times. Afraid I'll need a formula. I appreciate the tips though, that should help me check my work.

Not homework... geocaching puzzle. I haven't taken a math class in 16 years!
