Vector help

  1. Oct 15, 2009 #1
    1. The problem statement, all variables and given/known data
    Evaluate the divergence and curl of the following vectors.
    A(r) is everywhere parallel to the y-axis with a magnitude A = cx + A0 , where c and
    A0 are constants.

    2. Relevant equations

    3. The attempt at a solution
    I can evaluate the div and curl, but i dont know how to work out what the actual vector is, so can anyone help me work out what the vector is?

    [itex]\vec{j}[/itex] is "parallel to the y axis". [itex]\vec{i}[/itex] is parallel to the x axis. So any vector that is "always parallel to the y axis" must be of the form [itex]A\vec{j}[/itex].
