Dec6 revised Finding the catenary curve with given arclength through two given points Improve title. Dec6 suggested approved edit on Finding the catenary curve with given arclength through two given points Dec6 revised It is physically intuitive that the catenary is unique?

Note that the overlap of u and v are weighted by their mutual overlap with (the z-component of) w on the surface. It's a bit hard to pin down what my actual question is, but I think it has two parts: (1) is this "dot product of three vectors" a recognizable thing in mathematics with desirable properties? If so, why have I never seen it before, unlike the case with just 2 vectors. And, (2), how do I know this is the correct normalization?

I find it kind of mesmerizing. Mar21 comment Etymology of the word “pole”? Yes, I guess the word 'pole' is probably related to its usage in monopole, dipole, ..., multipole, etc.
