Verify that the functions cos 3x and sin 3x are solutions of the differential equation y" + 9y = 0 on the interval (-∞, 00). Then use the Wronskian to show that they form a fundamental set of solutions. Finally, write the general solution for the differential equation. The function v. = x2 is one solution of the differential equation r2y" – 2ry! 1 2y - O Use
