If your first attempt at using the integral test yielded divergence, it is probably because the interval on which you are integrating is not well-chosen. Precisely, it is likely that the integrand is not well-defined and/or monotone increasing on this interval (and this is required in order for the integral test to give the correct result). Change your bounds of integration and try again.
