Question

Transcribed Image Text:**Problem 2:**
For an underdamped system \((\beta < \omega_0)\), the two solutions can be written as \(x_1(t) = e^{-\beta t} \cos \omega_1 t\) and \(x_2(t) = e^{-\beta t} \sin \omega_1 t\).
(a) Show that as \(\beta \to \omega_0\), \(x_1(t)\) approaches the critically damped solution \(e^{-\beta t}\).
(b) What happens to \(x_2(t)\)? Show that the expression \(x_2(t)/\omega_1\) (which is still a valid solution to the underdamped system) approaches the second critically damped solution \(t e^{-\beta t}\) in the limit \(\beta \to \omega_0\).
