31 EXERCISES 2 show that the system x = x-sint with x(0) = 1/2 admits the periodic solution x(t) = (1/2) (sint + cost). How does this reconcile with our claim that id autonomous systems do not admit periodic solutions? ③ Likewise show that the system X = - w ² x with x (0) = 0 admits the periodic solution x(t) = sin (wt). Again, how do we reconcile this paradox?

2 show that the system x = x-sint with
x(0) = 1/2 admits the periodic solution
x(t) = (1/2) (sint + cost). How does this
reconcile with our claim that id autonomous
systems do not admit periodic solutions?
③ Likewise show that the system X = - w ² x
with x (0) = 0 admits the periodic solution
x(t) =
sin (wt). Again, how do we reconcile
this paradox?
