The roots of the auxiliary equation m2 +9 = 0) is m m = +3 m = + 3i None of these Om = i + + 3
The order of the differential equation xy" + xy' + (x2 – 16)y = 0 is - 0 1 O 2 O 3 O4
The complementary function of dạy differential equation +w2y = 0) is dx2 O CF = ci e@x – C2 @@x = - O CF = ci e@x + c2 e@x c1 enx = O CF = ci cosox + c2 sinox O CF = ci cosox – C2 sinox
