The components of a tensor.

  1. Jun 13, 2013 #1
    Hi,
    1. The problem statement, all variables and given/known data
    The components of the tensor Ai j are A1 2 = A2 1 = A, whereas all the other components are zero. I am asked to write A(BAR)i j, following a transformation to a new coordinate system, given that ∂q(BAR)k/∂qn = Rnk. I am expected to write my answer in terms of R.


    2. Relevant equations



    3. The attempt at a solution
    I know that A(BAR)i j = ∂q(BAR)i/∂qm * ∂q(BAR)j/∂qn * Am n
    But how may I proceed?

    I am wondering why no one has yet replied to this question.
    Nevertheless, if any one is reading this, I'd appreciate some help with this.
    I happen to know that the answer is:
    [itex]\bar{A}[/itex]ij = RilRjmAlm, but how may I bring under account the fact that Axy = Ayx = A?
