Hypotrochoid
Is there a diagram or picture of this movement or design? Anything to illustrate the word. — Preceding unsigned comment added by 70.183.237.150 (talk • contribs) 14 August 2006

File:HypotrochoidOutThreeFifths.gif to appear as POTD soon
[edit]Hello! This is a note to let the editors of this article know that File:HypotrochoidOutThreeFifths.gif will be appearing as picture of the day on July 25, 2010. You can view and edit the POTD blurb at Template:POTD/2010-07-25. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! howcheng {chat} 18:00, 23 July 2010 (UTC)
Moving the larger circle instead
[edit]What is it called when the moving circle is actually larger than the fixed one, not smaller? I don't mean an epitrochoid, where the moving circle is rolling around on the outside of the fixed one; I mean basically take the exact same initial setup shown here to illustrate a hypotrochoid (smaller circle inside and tangent to larger one), but then attach the point to the larger circle, and move the larger circle "around" the smaller, now-fixed, inner circle. What's that called? Is it still called a hypotrochoid? - dcljr (talk) 20:47, 20 October 2015 (UTC)
