Consider a damped oscillator with p < No. There is a little difficulty defining the "period" r1 since the motion (5.38) is not periodic. However, a definition that makes sense is that r1 is the time between successive maxima of x (t). (a) Make a sketch of x (t) against t and indicate this definition
