    We start by finding the eigenvalue. We know this equation must be true: Av = λv Next we put in an identity matrixso we are dealing with matrix-vs-matrix: Av = λIv Bring all to left hand side: Av − λIv = 0 If v is non-zero then we can (hopefully) solve for λ using just the determinant: | A − λI | = 0 Let's try that equation on our previous … See more
