Suppose A(3,-1,0) and B(-4,-2,3) are 2 points in 3-space. Find a vector with the following three characteristics: initial point at the origin, collinear but in the opposite direction of vector AB , length 3© BrainMass Inc. brainmass.com October 10, 2019, 2:02 am ad1c9bdddf
The vector that is parallel to the line segment connecting A and B has the components

If we place the initial point of this ...
