Write vector AB that goes from
point A (1,1,-4) to
point B (3,0,-1)
Do you just subtract the values of B from A?
<3-1,0-1,-1-4>
Whoops, I meant subtract the values of A from B.
Yes, that works
Yes, to find the vector that goes from point A to point B, we subtract the coordinates of point A from the coordinates of point B.
So, to find vector AB, we can subtract the values of B from A as you mentioned.
AB = B - A
= (3, 0, -1) - (1, 1, -4)
= (3-1, 0-1, -1-(-4))
= (2, -1, 3)
Therefore, the vector AB that goes from point A (1, 1, -4) to point B (3, 0, -1) is <2, -1, 3>.
