    (Fun) 3. Find the general solution using the method of undetermined coefficients:
    y" - 2y' - 3y = t +e^-t

    (More Fun) 4. Find the general solution using the method of undetermined coefficients:
    y" + 4y = [sin(t)]^2
    (Hint: Express sin²t in terms of cos2t)

    (Most Fun) 5. Find the general solution using the method of undetermined coefficients:
    y" + 2y' + 2y = e^(-x) cosx.
