(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 sinÂ²t in terms of cos2t)

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