This is what i got but it says it is wrong.

for my eigenvalues i got

and

from my eigenvalue of i got the eigenvector of

from my eigenvalue of i got the eigenvector of

so for my S matrix i got

S =

D =

Can you see what i did wrong?

Never mind i got it. the 1/6 is supposed to be a -1/6 (Rofl)

Thanks again for the help
