Question
! The matrix eigenvalue problem Mv = Av can be written as a set of homogeneous linear equations (M -
A1)v = 0. For this set of equations to have a non-trivial solution, we need to find possible eigenvalues A
that satisfy the secular equation det(M – A1) = 0.
O Show that the secular equation for an arbitrary 2 × 2 matrix ( 2) can be solved exactly by a quadratic
formula.
