What is Plane?

Definition 31.4 High School Mathematics · Chapter 31 — Vectors, Lines and Planes in Space

The plane through AA directed by two non-collinear vectors u,v\vec u, \vec v is the set of points MM with AM=su+tv\vect{AM} = s\vec u + t\vec v, (s,t)R2(s, t) \in \R^2.

Left: the line through A with direction u, graduated by the parameter t. Right: the plane through A directed by u and v; every point M of the plane is reached as AM = s u + t v. Left: the line through A with direction u, graduated by the parameter t. Right: the plane through A directed by u and v; every point M of the plane is reached as AM = s u + t v.
