This article needs a major edit: The kappa curve's equation is r= a*cot(θ). —Preceding unsigned comment added by 173.25.250.145 (talk) 08:14, 16 September 2009 (UTC)

Stub?
What do you think, how much information can we yet add about the curve? Is the stub notice still necessary? --Pt 23:46, 3 Oct 2004 (UTC)
 * I compared the amount of text with some other articles about curves. I reached a conclusion that this article is not a stub anymore. I removed the notice. --Pt 21:19, 4 Oct 2004 (UTC)

Implicit derivative
In the text the implicit derivative changes the roles of x and y that is given in the definition. It would be clearer if it were consistent. — Preceding unsigned comment added by 186.18.76.220 (talk) 18:43, 13 November 2011 (UTC)
