Fourier series problem
Please give me a help to find the answer for the following Fourier series question:
Find the steady state oscillation corresponding to
(d^2y)/(dx^2)y + c dy/dx + y = r(t) , where c > 0 and
r(t)=(pi*t)/4 if (pi)/2<t<(pi/2)
r(t)=[pi*(pit)]/4 if (pi/2)<t<[(3*pi)/2]
and r(t)=r(t+2*pi)
{the same is you can see the attached file here}
please be kind enough to help this my homework question.
