In this case the general solution of the differential equation in Equation 13.2.2 is. y = e − 3x / 2(c1cosωx + c2sinωx). The boundary condition y(0) = 0 requires that c1 = 0, so y = c2e − 3x / 2sinωx, which holds with c2 ≠ 0 if and only if ω = nπ, where n is an integer. We may assume that n is a positive integer.

First we need to find the eigenvalues of A. Recall that they are the solutions of the equation det (λI − A) = 0. In this case the equation is det (λ[1 0 0 0 1 0 0 0 1] − [ 5 − 10 − 5 2 14 2 − 4 − 8 6]) = 0 which becomes det [λ − 5 10 5 − 2 λ − 14 − 2 4 8 λ − 6] = 0.
