Matrices question

  1. Jan 11, 2008 #1
    i am given a formula and asked to find the ker
    of the matrices of the standart base

    this is the link were i tried to solve it:


    when i try to find the ker (T)

    i get all zeros

    i dont know where i get it wrong

    my theory says that after we simplify the matrix

    so i built equation and all i get is all zeros
    and that not the answer in the book
    where did i got it wrong?
