This actual German page hints the Hundekurve is actually the more general conchoid of Nicomedes. 142.177.24.163 04:53, 19 Aug 2004 (UTC)

The tractrix is not a conchoid. -phma 17:43, 28 Aug 2004 (UTC)

See de:Hundekurve - depending on the problem, the trival name "dog's curve" is either a conchoid, a tractrix, or a (straight) curve of pursuit --W!B: 01:31, 18 November 2005 (UTC)


I think that using a "dummy variable" t instead of x in the expression

y = \int_x^a\frac{\sqrt{a^2-t^2}}{t}\,dt

would be a less confusing notation. Mark.howison 03:47, 14 December 2005 (UTC)
