9. Consider the forced spring-mass system governed by the equation y" + 2y + 2y = 2 cos(t) Find the general solution to the differential equation. Identify the fundamental set for solutions to the corresponding homogeneous equation and the particular solution to the nonhomogeneous equation that appears in your general solution. Solve the IVP with initial conditions y(0) = 2 and y'(0) = 0. Find a different fundamental set for solutions to the homogeneous equation and a different particular solution to the nonhomogeneous equation.
