I have a simple question again:
I have this problem:
Given the points P(2,0,0). Q(4,3,-2) and R(-2,0,5) Find the coordinates for point S so that PQRS creates a parallelogram.
What i have tried is this:
Found the vector QP and the vector QR and then found S = WP + QR and that gave me [-9, -6, 5] and this does not conform with the answer in the textbook at all which is (-4,-3,7)
