Consider the differential equation y '' − 2y ' + 10y = 0; ex cos(3x), ex sin(3x), (−[infinity], [infinity]). Verify that the given functions form a fundamental set of solutions of the differential equation on the indicated interval. The functions satisfy the differential equation and are linearly independent since W(ex cos(3x), ex sin(3x))
