Question

Find the component form for vector AB given the initial point A (1, 7, -9) and terminal point B (-2, 18, 4).

Answer 1

To find each of the components of AB we can find the different between the components on the terminal and initial points, doing that, we find:

AB = (-2 - 1, 18 -7, 4 - (-9)) = (-3, 11, 13).
