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.
