This piece of "Art" is an overlay of the curves of several equations.

Identify as many as you are able by a generic name rather than attempting to offer the exact equation which was graphed.

(In reply to I spy by Jer)

When I was looking for various equations to graph I found the inverted cycloid but it was not named as such.  I'm sure that you know it, and a special property which it possesses.

 (After I had completed the image I realised that there was one, on my list, but overlooked, an ellipse.)
