matrix is:
0,0,1
1,0,0
0,1,0
Find eigenvalues of matrix.
Really stuck on how to do this as I work it out using the only method I know and get (0-λ ) (λ^2) + (λ ). Obviously a solution is 1 but I need to find two more??
Thanks.

$\displaystyle det \begin{pmatrix} 0-t & 0 & 1 \\ 1 & 0 -t & 0 \\ 0&1&0-t \end{pmatrix}$
$\displaystyle det \begin{pmatrix} -t & 0 & 1 \\ 1 & -t & 0 \\ 0&1&-t \end{pmatrix}$
Sarrus:
(-t)*(-t)*(-t) + 0*0*0 + 1*1*1 - 1*(-t)*0 - 0*1*(-t) - (-t)*0*1 = -t^3 +1
