Freya Holméryou've heard of sine and cosine
now get ready for uh squine and cosquare
j_bertolotti@acegikmo AKA as "sine and cosine in the taxicab metric" 😃
TobyBartels@j_bertolotti @acegikmo : The circle in the taxicab metric (l¹) is a diagonal square with half this size. This is the circle in the l^∞ metric (which doesn't have a cute name as far as I can remember).
Andrew@TobyBartels @j_bertolotti @acegikmo i think it's sometimes called the chessboard metric, as it's kind of "distance in king's moves"?
@TobyBartels @andrewt @j_bertolotti I've usually hear it called Chebyshev distance, but idk how commonly used it is!
or max-norm or something of the kind
there's also rectilinear distance but I always forget if that's taxicab or chebyshev
@acegikmo @TobyBartels @j_bertolotti I think I did use it in my PhD but only really to speed up a calculation, it wasn't actually *better* for anything
