📚 Osculate, verb. 🔉 /ˈɒskjʊleɪt/ 🇬🇧 ❓ Definition (with object • Mathematics): (of a curve or surface) touch (another curve or surface) so as to have a common tangent at the point of contact. ❗️ Examples: 1. The plots have been drawn using osculating orbital elements. 2. If seven points on a twisted cubic be joined, two and two, by twenty-one lines, then any seven planes that contain these 21 lines will osculate a second cubic curve. 3. Should the students be asked to sketch the osculating circle to a given curve at a given point, and then notice that as the point of contact changes, the radius of the circle is inversely proportional to the measure of curvature? ━━━━━━━━━━━━━ 🌀 @cambridge_dic
