Homework Help: Eigenvalue/vector M^n=PD^nP^-1

  1. Nov 2, 2007 #1
    1. The problem statement, all variables and given/known data


    3. The attempt at a solution

    First I found eigenvalues/vectors. Eigenvalues = 0, 3. Associated eigenvectors are (1,2) and (1,1). P= matrix of e. vectors, D = matrix of values.



    Not really sure where I'm going wrong, have gone through it a few times, but my answer is only 50% correct according to the computer program.

    Recalculate the inverse of P. Sign error in row2, column1, it should be 2 and not -2.

    You also have P and P -1 reversed.
