Unformatted text preview: Î» 1 + Î» 2 equals trM , and that Î» 1 Î» 2 equals detM (the two invariants of M ). For the second matrix, what conditions on b and c will make M positive deï¬nite? 4. Keener 1.2.4 (p.51) 5. If A is a Hermitian matrix, show that 1) all eigenvalues are real, 2) if two eigenvalues are distinct, then the corresponding eigenvectors are orthogonal. 6. Show that A * = Â¯ A T for h x, y i = Î£ x i Â¯ y i 7. Keener 1.2.5 (p.51) 8. If A and B are positive deï¬nite matrices and Ax = Î»Bx , where Î» is a scalar, show that Î» must be positive....
