Question:
(a) Solve the initial value problem y" + y = cos ?t, ?2 ? 1, y(0) = 0, y' (0) = 0. Show that the solution can be written
(b) Experiment with the solution by changing ? to see the change of the curves from those for small ? (>0) to beats, to resonance, and to large values of ? (see Fig. 60).
