Osculating Circle/Sphere
Osculating Circle
Let C be a space curve with three neighbooring points P,Q, R on it. Then Osculating circle at P is defined as the limiting position of the circle through P,Q,R as Q,R approaches to P.
Mathematically,
Osculating circle at P= circle through P,Q,R
Osculating Sphere
Let C be a space curve with three neighbooring points P,Q, R,S on it. Then Osculating sphere at P is defined as the limiting position of the sphere PQRS as Q,R,S approaches to P.
Mathematically,
Osculating sphere at P= sphere through P,Q,R,S
