Did you carefully complete the reading assignment?
A general solution to equation 1.11 in the reading is x(t) =
Aeiωt, where A is complex in general. Plug this
general solution into equation 1.11. Explicitly write down your
solution, separate the real parts from the imaginary parts. What do
you find? How does your answer make sense, given the fact that
friction is at work here?
If you plotted (the real part) of your solution to the previous
question, what would it look like? How can there still be a frequency
in the problem (there is, how does that work?)
Was there anything that you didn't understand in the reading
assignment? If so, explain.
