Plz solve all
h (h) (D? + 6D+9) e 3. = 23 Ans y = e-3. 2.2 = = (i) (D2 +9)y = sec 3x Ans y = { sin 3x + į cos 3x · log(cos 3x) (j) (D2 + 3D + 2)y = x sin 2x = Ans y = (302-7) 200 COS 2.x 5.0-12 sin 2x 100 3. Solve the following Differential equations (a) (D2 + 5D – 6)y = sin x sin 4x Ans y = clea + c2e-6x + 2 [si = 1f sin 3.x-cos 3.2 30 + 31 cos 5.3-25 sin 5. 1586 25 sin 51)
