Talk:Radius of curvature

Article creation
This page was created from material in the Intrinsic equation article where it was more or less off-topic. Rather than simply deleting it I moved it here. There are already several curvature related articles so this material may be redundant and this article could theoretically be merged with an existing article. The situation is rather messy however and exactly which article it should be merged with is unclear (at least to me).--RDBury (talk) 17:30, 13 July 2008 (UTC)

Radius of curvature (mathematics)
Can radious of curvature be negative?

Shouldn't it be the reciprocal not the inverse in that first part? — Preceding unsigned comment added by 134.197.92.253 (talk) 01:00, 22 January 2016 (UTC)
