"WebAug 10, 2024 · If the 2 dimensional matrix A has 2 eigenvalues x and y, then T r ( A) = x + y and d e t ( A) = x y. So then we have the equation x + y = x y which transforms to: y = x x − 1 Set some value of x, and you'll get a value of y. You should then be able to choose any two linearly independent eigenvectors you want. " - Determinants of 2x2 matrix
