Video transcript. We figured out the eigenvalues for a 2 by 2 matrix, so let's see if we can figure out the eigenvalues for a 3 by 3 matrix. And I think we'll appreciate that it's a good bit more difficult just because the math becomes a little hairier. So lambda is an eigenvalue of A.

A = [ 3 0 0 3]. 🔗. A has an eigenvalue 3 of multiplicity 2. We call the multiplicity of the eigenvalue in the characteristic equation the algebraic multiplicity.

$\begingroup$ @PutsandCalls It’s actually slightly more complicated than I first wrote (see update).

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.
