A Geocaching triangulation problem: Given three pairs of lat/lon coordinates, and a distance from each, find a third pair of unknown lat/lon coordinates.
Figured out how to do this by construction using a map and some dividers, but it seems that there must be a better way to do it by HP calculator. Which calculator would be ideal for this?
My wife grabbed her TI-83 and said it was best, but I maintain that one of my old HPs must be better. Problem is, I have so many of the damned things I can't choose which is best to solve the problem. See what you think:
