I ask this because all the examples I have seen of the "comparison test" try to compare that series to a series in the "p-series form" where you can tell straight away if it's convergent by looking at the power of the bottom variable. The problem is that I have trouble finding proper comparisons because I get all confused. So is it wrong if I use both a comparison and an integral test in unison?
