A parametric surface is a surface defined by a parametric equation, involving two parameters. Are parametric surfaces limited to two parameters? I could imagine that it is possible to come up with parametric surfaces that have more (or maybe even less) parameters. What about parametric curves? Can they be thought of as parametric surfaces limited to one parameter? -- Abdull 15:50, 30 May 2006 (UTC)
While its true that calculus textbooks may use any pair of variables as parameters for a general parametrized surface, I think that it's a really bad idea to mix up the notation within the same article; forget the article — within the same paragraph even! This is totally schizophreniac. Most modern differential geometry books use u and v, why not stick to them throughout? Arcfrk ( talk) 05:01, 11 March 2008 (UTC)
I believe that this article errs in that a sphere is parametrized by (sin(theta)cos(fi), sin(theta)cos(fi), cos(theta)), with the bounds given on the page. —Preceding unsigned comment added by 128.113.232.35 ( talk) 19:10, 10 April 2009 (UTC)

Why is there no category for these types of surfaces? It makes searching for them more difficult. SharkD Talk 22:26, 24 August 2013 (UTC)
