WebApr 27, 2024 · Example 1: Find the eigenvalues for matrix A Thus This is the characteristic equation. Solving for λ, we have the eigenvalues λ = 3 and λ = 14. Observation: Let A = . Then Thus Now let λ1 and λ2 be the eigenvalues. Then (λ – λ1) (λ – λ2)=0, and so λ2 – (λ1 + λ2)λ+ λ1 λ2, and so λ1 + λ2 = trace A and λ1 λ2 = det A. WebCase : The associated eigenvectors are given by the linear system. which may be rewritten by. Many ways may be used to solve this system. The third equation is identical to the first. Since, from the second equations, we have y = 6 x, the first equation reduces to 13 x + z = 0. So this system is equivalent to.
