Find a nonzero vector orthogonal to the plane through the points P, Q, and R.? Consider the points below.

Question

P(0,-3,0), Q(4,1,-3), R(5,3,1)

Answer 1

vector PQ = <-3,4,4>
vector PR = <1,6,5>
Now take the cross-product between these two vectors, using whichever method you learned.
To test your answer, the dot product of your answer vector with both PQ and PR must be zero.
