3 Dimensional diagram, but no mention of 3 Dimensional Lissajoux figures[edit]

the second diagram on the page is described as a lissajoux curve in 3D, but there is no mention of Lissajoux curves with more than 2 dimensions on the page. stib (talk) 12:37, 8 March 2009 (UTC)

Conflict with Spirograph page[edit]

The webpage for Spirograph states that (paraphrased) spirograph drawings look similar and are based on similar math, but this page states that spirograph drawings look similar but have somewhat different math. Neither is backed by a reference. --Edgriebel 19:15, 8 September 2006 (UTC)

What are the parameters?[edit]

Please describe what the parameters mean, their limits etc. -SharkD 00:41, 1 November 2006 (UTC)

Diagram and description at odds[edit]

The phase shift/ratio diagram and the general description of the curve are at odds. The article states that a parabola is gotten by phase shifts of pi/2, while the diagram shows a parabola at pi/4. -SharkD 20:10, 1 November 2006 (UTC)

a:b ratios are wrong[edit]

November 2006 a & b ratios shouls be inverse through out the whole article. (eg. If the article says a:b=1:2 the graph is actually a:b=2:1) This error is consistent in the whole article.

Animated?[edit]

Would an animated lissajous curve be a helpful addition? I think that done from the right angle, it could show the circular nature nicely. Regards, Ben Aveling 11:22, 30 January 2008 (UTC)

Lissajous Pronunciation[edit]

It might be a good idea to show how to pronounce Lissajous? —Preceding unsigned comment added by Sero12 (talkcontribs) 10:03, 5 March 2008 (UTC)

Done. I say it LEE-suh-zhoo, and I think that's right, but I welcome edits. —TedPavlic | (talk) 15:16, 15 October 2008 (UTC)

The pronunciation is "Lee-sah-ju", since in French the double s between two vowels makes a soft s sound. The final s is also silent. —Preceding unsigned comment added by 147.188.32.118 (talk) 12:36, 12 August 2010 (UTC)

Ok. Done. Thanks. —TedPavlic | (talk) 21:12, 2 January 2009 (UTC)

wrong phase shift in examples section[edit]

in all other works about lissajous curves examples shown in the example section are for phase shift 0 or pi, not the pi/2. this is also true from my own experiments —Preceding unsigned comment added by 89.228.251.75 (talk) 21:56, 12 March 2011 (UTC)

External links[edit]

I cleaned up the External links section because it seemed to be a WP:SPAMHOLE with links to personal web sites, blogs, directories of shareware, etc per WP:LINKSTOAVOID and WP:NOTDIRECTORY. Per WP:SPAMHOLE I did an incomplete (incompetent?) removal so other editors can remove more, or restore some if there is a reason per policy and guidelines to keep them.
