I received the following question:

"To calculate the damping coefficient is it sufficient to use, damping ratio = delta / sqrt(4*pi^2 + delta^2), where delta = 1 / n * ln(B1 / Bn+1), and B1 is a peak of the wave followed by Bn+1 being a peak of the wave "n" cycles way, is this an acceptable method to use?"

This is the log-decrement method mentioned in the Lab 2 lecture slides, and is definitely one method to calculate damping ratio. In general, the lectures given on Monday (and to some extent on Friday) are always going to pertain to methods and theory you will need to complete your lab reports. Obviously, the Friday lectures are more geared towards the TechCom side of the report.

Actually, this brings up an overarching issue for a new sticky I will post in the Lab 2 forum that I think everyone should read.
