Appearance
In mathematics, Poinsot's spirals are two spirals represented by the polar equations
where csch is the hyperbolic cosecant, and sech is the hyperbolic secant.
This is an old revision of this page, as edited by 190.1.10.179 (talk) at 18:10, 16 May 2010 (Well, couldn't see the equations, so I edited it and now it can be seen. But I'm not familiarized with this topic, so someone who does should give it a view, and correct it if necessary.). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.
