5.Find the general solution of the following differential equation. y"+4y'+4y=sin2x

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.
