Question:

Use the result of Exercise 61 to determine whether the points P, Q, and R are collinear, and if not, find a vector perpendicular to the plane containing them.

(a) P = (2, 1,0), (b) P = (2, 1,0), (c) P = (1, 1,0), Q=(1,5,2), R=(-1, 13, 6) Q= (-3,21, 10), R=(5,-2,9) Q =


Data From Exercise 61

Show that three points P, Q, R are collinear (lie on a line) if and only if POX PR = 0.
