For part (c) of the Check Your Understanding 14.10 I got 1800 rad/s for the angular frequency, am I right? The book gives the answer as 1.4 * 10^3 rad/s. Also for part (b) I got -pi/2 rad, but the answer is pi/2 rad and -pi/2 rad. I'm not sure where the pi/2 came from. I've attached the problem below. Please don't solve the example but the questions after it. Example 14.6 An LC Circuit In an LC circuit,...
