2 President UniversityErwin SitompulMVC 2/2 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. 12.4 The Cross ProductChapter 12

7 President UniversityErwin SitompulMVC 2/7 Distance and Spheres in Space Example Chapter 1212.4 The Cross Product Example

8 President UniversityErwin SitompulMVC 2/8 Lines in Space Chapter 1212.5 Lines and Planes in Space Suppose L is a line in space passing through a point P 0 (x 0,y 0,z 0 ) parallel to a vector v. Then L is the set of all points P(x,y,z) for which P 0 P is parallel to v. P 0 P = tv, for a given value of scalar parameter t.
