The term derives from the Latinate root " osculate ", to kiss, because the two curves contact one another in a more intimate way than simple tangency.

:I'm not well-versed on the mathematics involved, but you might be able to construct the parabola by treating the log as an osculating circle.
23.
Post release of theatrical trailer, it was revealed that the filming of ten second osculating scene between lead actors took four hours to complete after several re-takes.
24.
The osculating plane in the geometry of Euclidean space curves can be described in terms of the Frenet-Serret formulas as the linear span of the tangent and normal vectors.
25.
Or, in other words, if the torsion is zero, the curve lies completely in the same osculating plane ( there is only one osculating plane for every point ).

27.
If " C " is a regular space curve then the osculating circle is defined in a similar way, using the principal normal vector " N ".
28.
These estimates are easiest to derive when the manifold is strongly pseudoconvex, for then one can replace the manifold by osculating it to a high enough order with the Heisenberg group.
29.
:: If the osculating circle has radius 1, the parabola is given by 2 " " x " 2; but this does not give a satisfactory solution.
30.
If the derivative of curvature ?'( " t " ) is zero, then the osculating circle will have 3rd-order contact and the curve is said to have a vertex.
