6. Solve the following initial value problem. y'"-2y"+4y'-8y=0,y(0)=-1, y'(0)=30, y"(0)=28,

2.4 If we add a constant valie of one to x(t), we obtain the signal y(t) = 1 + x(1) with y(t) given overone period by The signal can be represented by a Fourier series, but with different coefficients: Explain how bo and b! are related to ao and a . Note: you should not have to evaluate any new integralsexplicitly to answer this question.
