- Taylor's Equation 5.68 is an essential one for what we're doing this week (and next). Under it he says, "You need to think very carefully about this potentially confusing formula". So... please think very carefully about this equation, and in your own words, try to explain it to us!
- After a long time, is the frequency of vibration of a driven, damped harmonic oscillator...
Greater than...
Less than...
equal to..
I'm really not sure!
(not answered)
...the driving frequency?
- Exams don't stop the class! Please submit a question you have about the reading assigned for the upcoming class. What seemed hard, was something confusing, what would you like us to spend class time on? If you can't come up with any question, how about a comment - (did anything strike you as interesting? )
Reminder: the reading assignments are on our course calendar
Thanks for your time.
