Consider a driven undamped spring/mass system described by the initial-value problem

(a) For n = 2, discuss why there is a single frequency at which the system is in pure resonance.

(b) For n = 3, discuss why there are two frequencies at which the system is in pure resonance.

(c) Suppose and F0 = 1. Use a numerical solver to obtain the graph of the solution of the initial-value problem for n = 2 and in part (a). Obtain the graph of the solution of the initial-value problem for n = 3 corresponding, in turn, to in part (b).
