So far in this chapter, we have primarily discussed series with positive terms. WebWhen asked to show if a series is convergent or divergent you might spot that such series is "mimicked" by a positive, decreasing and continuous function (there's no fixed rule, you have to train your mind to recognize these patterns). If that is the case you can use the integral test to say something about the series and back it up properly.
