Talk:Tractrix

From Wikipedia, the free encyclopedia

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)

[edit] Merger

Yes to merging tractrice into this page. Richard Pinch 06:31, 9 October 2006 (UTC)

[edit] Pseudo-latin terms

I removed the terms tractendus and tractens for the pulling resp. pulled object. For one, they should be reversed (-endus is passive while -ens is active), for another the correct classical latin forms would be trahens and trahendus. And anyway, it's been a while that latin was the lingua franca of mathematics. HannsEwald 11:23, 18 January 2007 (UTC)
