Using I can prove the integer satisfied necessary condition but it is not sufficient. On the other hand in convergence tests limes to zero say nothing (I mean limit comparison test). Maybe I am wrong?

What I intended to say is that for x 'large enough' is...
(1)
... no matter 'how small' is . Now the integral...
(2)
.... converges for all , so that also Your integral converges...
