- 6(a)(i)Find the general solution of the differential equation
(1 + x^2) \frac{\mathrm{d}y}{\mathrm{d}x} + 2xy = \sqrt[3]{x}.[7 marks] - 6(a)(ii)Hence, given that
y = 2whenx = 0, calculatey(1).[3 marks] - 6(b)(i)Use the substitution
u = y'to show that the differential equationy'' + 4y' = 2\cos 3x - 4\sin 3xcan be reduced tou' + 4u = 2\cos 3x - 4\sin 3x.[2 marks]
