Summary: The LO addresses how to derive the value of the damping constant and the percentage of amplitude lost after a specific number of oscillations. It takes a different approach then the example from the textbook and solidifies the idea of the frequency of damped harmonic oscillators. I chose a pdf file for this LO as I found it the easiest to follow.
