Talk:Cayley's sextic

More

Paper it was discussed in first - note on anharmonic ratio sextic??
2 cartesian equations (or more)
applications - quantum physics? Or is that better in sinusoidal spirals?
Bibliography?

Two-dimensional curve?

What does "two-dimensional curve" mean? Should it be "plane curve"? Deltahedron (talk) 21:28, 10 April 2014 (UTC)[reply]

Parametric representation

The section Cayley's sextic#Equations of the curve says

Cayley's sextic may be parametrised (as a periodic function, period π ℝ→ℝ²) by the equations

x = cos³t cos 3t
y = cos³t sin 3t.

The node is at t = ±π/3.

~~This seems wrong in two respects. First,~~ the equation as previously presented in Cartesian or polar form has a parameter a that is missing here. ~~Second, according to the displayed graph, the node is at (0,0), while this says the node is at (–1/8, 0).~~ Loraof (talk) 23:16, 22 April 2018 (UTC)[reply]
