Osculating Plane
The Plane spanned by the three points 
, 
, and 
on a curve as 
. Let 
be a point on the osculating plane, then
where
denotes the Scalar Triple Product. The osculating plane passes through the tangent. The intersection of the osculating plane with the Normal Plane is known as the Principal Normal Vector. TheVectors 
and 
(Tangent Vector and Normal Vector) span the osculating plane.See also Normal Vector, Osculating Sphere, Scalar Triple Product, Tangent Vector- L-System
