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.

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 ). no, this is wrong you get 1-t^3 and therefor one eigenvalue is +1 Originally Posted by geo3 Obviously a solution is 1 but I need to find two more?? No, you do not.
how did you calculate 1-t^3??

Sarrus: (-t)*(-t)*(-t) + 0*0*0 + 1*1*1 - 1*(-t)*0 - 0*1*(-t) - (-t)*0*1 = -t^3 +1
