    1. The problem statement, all variables and given/known data

    which of the following pairs of quantities transform under rotations of the axes as the components of a two-dimensional vector?
    a) (x2, -x1)
    b) (x2,x1)
    c) ((x1)^2,(x2)^2)
    2. Relevant equations

    3. The attempt at a solution
    Dont know where to start. i'd appreciate just a little guidance :)

    I'm not quite sure what you mean by that. If you mean does the transformation L((x1,x2))=(x2,-x1) (for a)) correspond to a rotation by some angle theta, look at the formula in your other post and see if it corresponds to some value of theta.
