    [SOLVED] Vector Spaces

    Could someone explain this question to me.

    Express the given vector in terms of its coordinates.

    The vector from the origin to the initial point of the vector to (6, 4, -3) in the opposite direction and with twice the length of (-2, 3, 4).

    If I understand your question correctly you are looking for:

    \vec v = (6,4,-3)+(-1) \cdot 2 \cdot (-2,3,4) = (10,-2,-11)

    But I'm not certain because I don't know what an initial point of the vector could be.
