Repeating eigenvalues
In that case the eigenvector is "the direction that doesn't change direction" ! And the eigenvalue is the scale of the stretch: 1 means no change, 2 means doubling in length, −1 means pointing backwards along the eigenvalue's direction. etc. There are also many applications in physics, etc. In that case the eigenvector is "the direction that doesn't change direction" !

That is, the characteristic equation det(A−λI)=0 may have repeated roots. As any system we will want to solve in practice is an …1 Answer. Sorted by: 13. It is not a good idea to label your eigenvalues λ1 λ 1, λ2 λ 2, λ3 λ 3; there are not three eigenvalues, there are only two; namely λ1 = −2 λ 1 = − 2 and λ2 = 1 λ 2 = 1. Now for the eigenvalue λ1 λ 1, there are infinitely many eigenvectors. We say an eigenvalue λ1 of A is repeated if it is a multiple root of the char acteristic equation of A; in our case, as this is a quadratic equation, the only possible case is when λ1 is a double real root. We need to find two linearly independent solutions to the system (1). We can get one solution in the usual way.
