16. Suppose A is a 3 x 3 matrix with real entries that has a complex eigenvalue -5-8 with corresponding -6 - 52 eigenvector -1 . Find another eigenvalue and eigenvector for A. 52 Eigenvalue = Eigenvector = 17. Suppose y1 = xyl + 3y2 + sec(x) , y'2 = sin(x) y1 + xy2 - 4. This system of linear differential equations can be written in the form Y' = A(x)Y + G(x). Determine A(x) and G(x). A (x) = G(x) =
