    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*(pi-t)]/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.
