The Cross Product of Two Vectors in Space In space, we need a way to describe
how a plane is tilting. We accomplish this by multiplying two vectors in the plane together to get a third vector perpendicular to the plane
The direction of this third vector tells us the “inclination” of the plane.
We use cross product to multiply the vectors together.

Lines in SpaceChapter 12 12.5 Lines and Planes in Space
Suppose L is a line in space passing through a point P0(x0,y0,z0) parallel to a vector v.
Then L is the set of all points P(x,y,z) for which P0P is parallel to v.
P0P = tv, for a given value of scalar parameter t.
