Find a vector perpendicular to the plane and containing the given points.
(0,-2,2), (1,2,-3) and (4,0,-1)
Can anyone show me how to this problem?
Name the points $\displaystyle P0,-2,2), Q1,2,-3) ~\&~ R4,0,-1)$
Then find $\displaystyle \overrightarrow {PQ} \times \overrightarrow {PR} $. That is your answer.
