Anons merge proposal   It has been proposed that Euclidean space and Coordinate space be merged I dont think this is a good idea because theyre distinct concepts and I daresay a separate article can be written on each The article Euclidean space should emphasize the metric and refer to Coordinate space for the details of the coordinate representation the article Coordinate space should emphasize nonmetric representations of arbitrary vector spaces Euclidean space should briefly discuss On Coordinate space should briefly discuss GLn  And lest we forget something still has to be done about Coordinate vector
