QUESTION 2 a) Find the general solution of y" +y = cot r. b) The equation of motion for a certain damped mass-spring system is given by y" + 4y = 4 cos 21, y(0) = 0, y(0) = 1 where y = y(t) denotes the displacement of the mass from equilibrium at time t > 0. Solve this equation using the method of undetermined %3D coefficients.
