Homework Help: Adding 2 vectors together graphically

  1. Oct 1, 2012 #1
    1. The problem statement, all variables and given/known data
    When adding 2 vectors together graphically, which of the following may be done?
    A) moving a vector
    B) rotating a vector
    C) changing the length of a vector
    D) changing the angle between the vectors


    2. Relevant equations
    a = ax +ay


    3. The attempt at a solution
    I think it's rotating a vector but I'm not certain.

    Welcome to the PF.

    Why do you say that?

    Take two vectors, sketch them individually, and then sketch their addition. What did you do when you sketched their addition?

    A = [1,1]
    B = [2,3]
    C = ? (sketch the answer...)
