198 Economic Dynamics (i) Show that the characteristic roots of the system are r = 5 and s =− 1. (ii) Derive the eigenvectors associated with the eigenvalues obtained in (i). (iii) Show that the solution values are: x ( t ) = c 1 e 5 t + c 2 e t y ( t ) = c 1 e 5 t c 2 e t and verify that c 1 e 5 t ± 1 1 ² , c 2 e t ± 1 1 ² are linearly independent. (iv) Given x (0) = 1 and y (0) = 0 , show that x ( t ) = 1 2 e 5 t + 1 2 e t y ( t ) = 1 2 e 5 t 1 2 e t 6. For the dynamic system ˙ x = x + 3 y ˙ y = 5 x + 3 y Show: (i) that the two eigenvalues are r = 6 and s 2 (ii) that the two eigenvectors are v r = ± 1 5 / 3 ² and v s = ± 1 1 ² (iii) and that the general solution satisfying x (0) = 1 and y (0) = 3is x ( t ) = 3 2 e 6 t 1 2 e 2 t y ( t )
