Trace in terms of eigenvalues
Splet27. mar. 2024 · First we need to find the eigenvalues of . Recall that they are the solutions of the equation In this case the equation is which becomes Using Laplace Expansion, compute this determinant and simplify. The result is the following equation. Solving this equation, we find that the eigenvalues are and . Splet10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment.
