Talk:Tangent developable

"Parametrization": a doubt
"The original curve forms a boundary of the tangent developable" — really? Is the parameter s assumed to be positive? The union of tangent lines, or tangent rays? Boris Tsirelson (talk) 13:01, 10 June 2015 (UTC)

Hello. I can't add a link to the French article, called Développable des tangentes (conflict). Adam Bross (talk) 21:49, 27 August 2022 (UTC)
 * Fixed. The problem was that the French article was linked to a redirect to this article preventing it from being linked directly. —David Eppstein (talk) 21:56, 27 August 2022 (UTC)
