Problem:
Attempt:

I've been googling for examples on the internet how to do so, and my book does not show any examples either. What I've done was set both vectors at the same origin in two scenarios with the two given origins. I then accounted the change based on the origin (0,0,0) and counted points from there. For the origin (1, pi/2, 0) for instance, based on (0,0,0), I found the second component of AB by subtracting one point from the yaxis. So instead of 7(4), I got 6(3) which gave 3 (correct from answer in back).
This method worked for some components, but not for some, so now I am lost. Is there a proper way to doing this?
