Talk:N-ellipse

Maxwell or Descartes?
According to James Clerk Maxwell, "[Maxwell's] work [on N-ellipses] was not entirely original, since René Descartes had also examined the properties of such multifocal ellipses in the 17th century".

But this article says that "They were first investigated by James Clerk Maxwell in 1846."

Anybody like to clarify?

help, too many symbols

 * If n is odd, the algebraic degree of the curve is $2^k,$ while if n is even the degree is $2^k - \binom{k}{k/2}. $

May I suppose that n = k here? —:Tamfang (talk) 07:05, 8 July 2016 (UTC)
 * It must be. I've changed it to use n exclusively, since that is in the title. Double sharp (talk) 13:47, 15 March 2017 (UTC)

correspondence

 * The 1-ellipse corresponds to the circle. The 2-ellipse corresponds to the classic ellipse.

Is there a good reason not to change corresponds to to is? —Tamfang (talk) 20:16, 27 August 2016 (UTC)
 * Not that I can think of. ✅. Double sharp (talk) 13:46, 15 March 2017 (UTC)
