Homework Help: Ugh vectors

  1. Jan 21, 2009 #1
    Ok can someone help me. Its driving me crazy! and I know its really simple so the problem gives me points A and B:



    First it wants me to find vector AB
    so i did that :

    AB= <-4,-2>

    Now, I am confused cause it wants me to draw it and the equivalent representation starting at the origin. and i don't know how to do that.

    You can either draw a vector between (2,3) and (-2,1) or the equivalent vector between (0,0) and (-4,-2), right? They are the same, just with different origins.
