This is obviously true for perfectly "flat" surfaces - and, intuitively, it seems to be true for all other sorts of 2d surfaces. Is this a proven result? If so, can we generalize?; can we say a n-elements system of coordinates uniquely identifies a point on any n dimensional object? It carries on to 3 dimensions, I think this is more than obvious, but otherwise?(adsbygoogle = window.adsbygoogle || []).push({});
