Osculációs
Osculational is a term originating from differential geometry and calculus, referring to a high degree of contact between two curves or surfaces. When two curves are osculating, they not only touch at a point but also share the same tangent line and the same curvature at that point. This means they locally "mimic" each other very closely.
The concept can be extended to surfaces, where osculating surfaces share a common tangent plane and curvature
A key application of osculation is in the study of curvature. For a plane curve, the osculating
The degree of contact can be quantified. Two curves have contact of order n if their first
