Find vector whose tail & head are midpoints of

  1. Sep 8, 2012 #1
    1. The problem statement, all variables and given/known data
    Find the components of the vector v whose tail and head are the midpoints of segments AC and BC.

    A = (1,0,1). B = (1,1,0), & C = (0,1,1)


    3. The attempt at a solution

    I don't know what the question is asking about exactly? I find the wording very awkward.

    What is it you don't understand? Midpoints? Heads and tails?

    I take it to mean that the midpoint of AC is the tail of the vector, and the midpoint of BC is the head of the vector.

    Voko, see post below.

    Ohh.. that could be it. It would have helped if the author was a bit more careful with his wording. For example by saying:

    Find the components of the vector v whose tail and head are the midpoints of segments AC and BC respectively.

    or preferably

    Find the components of the vector v whose tail is the midpoint of segment AC and head is the midpoint of BC.
