Web5.(a) [5 marks] Find the scalar equation of the plane that contains the three points P(5,−1,2), Q(−1,3,4) and R(3,1,1). Solution: we have −−→ PQ = −1−5 3+1 4−2 = −6 4 2 and −→ PR = 3−5 1+1 1−2 = −2 2 −1 . For the normal to the plane, we can take ~n = −−→ WebSection 5.4 p244 Problem 3b. Do the vectors (3,1,−4),(2,5,6),(1,4,8) form a basis for R3? Solution. Since we have the correct count (3 vectors for a 3-dimensional space) there is certainly a chance. If these 3 vectors form an independent set, then one of the theorems in 5.4 tells us that they’ll form a basis. If not, they can’t form a basis.
