The original version of this article contained material copied directly from a copyrighted web page.
Here is a quote from this article: "Given a line, if we roll a conic along the line, the locus of the conic's focus is a curve C. The surface of revolution of C is called an unduloid. It is the minimal surface connecting two parallel circular discs on the same axis."
Here is the definition of an unduloid appearing at the University of Cambridge's maths thesaurus web page:
Given a line, if we roll a conic along the line, the locus of the conic's focus is a curve C. The surface of revolution of C is called an unduloid. It is the minimal surface connecting two parallel circular discs on the same axis.
I have removed the offending material from this article. I have also taken the matter up with User:N4nojohn, the author of this page. Depending on what he decides, I may or may not decide to expand this article to include all five species of "Delaunay surfaces". See this article. DavidCBryant 15:00, 23 May 2007 (UTC)
