Question
A suitable form of the particular solution of the non-
homogeneous ODE:
y" + 16y=e4x + x cos 4x
is
a) yp(x) = Ae4x + (Bx + C) cos 4x + (Dx + E) sin 4x
b) y(x) = Ax²e4x + (Bx + C) cos 4x + (Dx + E) sin 4x
c) yp(x) = Ae4x + Bx² cos 4x + Cx² sin 4x
d) yp(x) = Ae4x + x(Bx + C) cos 4x + x(Dx + E) sin 4x
e) y(x) = Axe4x + (Bx + C) cos 4x + (Dx + E) sin 4x
