    It's easier than you think tbh.

    I looked at your assignment sheet (15 :holmes:) and it starts you off with a 2x2 example. Have you managed to show that? Try use the hint of adding all the rows together.

    Let your matrix be:
    A=\begin{pmatrix}

x_{11} & x_{12}\\

x_{21} & x_{22}\end{pmatrix}

    You then know that:
    x_{11}+x_{21} = 0 and x_{12}+x_{22} = 0

    Recall that A\mathbf{y}=\lambda\mathbf{y}. In this case, assume that lambda = 1, dot product and :holmes:

    Whoops it's meant to be 1.

    Work it out and see what happens. Remember the tip to add up all the rows.

    Then extend this to an nxn matrix.
