A lumped model of a system is proposed consisting of a mass-spring system. The corresponding
mat mematical model developed in the form of an ordinary differential equation is given as
(d^(2)x)/(dt^(2))+12.25x=f(t)
Using Fourier series, find out the steady-state response x(t) of the system, when it is subjected to a
periodic function f(t) of time period 2\pi as defined below:
f(t)=1 for 0
