Homework Help: Linear Math Vector

  1. Nov 6, 2009 #1
    1. The problem statement, all variables and given/known data

    Find the vector u=(xyz) whose

    (i) initial point is the midpoint of (-2,-4,0) and (10,6,0)

    (ii) terminal point is the midpoint of (1,-4,4) and (5,8,-10)

    2. Relevant equations

    I know the midpoint for two vectors from say..P to Q is P+ (1/2) (Q1-P1 Q2-P2, Q3-P3)

    3. The attempt at a solution

    I can find mids for both..but am confused by the initial midpoint to terminal midpoint..what else do I need?

    i think read start & end of the vector u, for initial & terminal respectively. The midpoint just lets you find where they are
