I'm trying to calculate the euclidean distance between two points
(x2,y2) which is
sqrt( (x2-x1)^2 + (y2-y1)^2 )
Is there a way to calculate this easily with Emacs calc?
(I looked in the Info pages, but was not able to tell if there a way to do this easily. I can use
f h to compute the hypotenuse, but I can't figure out how to use that with points, or if Emacs has any first class notion of a point)
