Just with these two examples, we have shown that when L = 1, we cannot be sure of convergence or divergence. n^10 / n! is definitely not geometric, but the ratio test applies to all series. The geometric series test is just a specific case of the ratio test.Definition: A series that converges, but does not converge absolutely is called conditionally convergent, or we say that it converges conditionally. By definition, any series with non-negative terms that converges is absolutely convergent. The alternating harminic series is conditionally convergent.More formally, we say that a divergent integral is where an improper integral’s limit doesn’t exist. On the other hand, if the limit is finite and that limit is the value of the improper integral, the integral is convergent [1]. To put this in plain English, the term “integral diverges” means that you can’t calculate the area under a ...$\begingroup$ I think this is an interesting answer but you should use \frac{a}{b} (between dollar signs, of course) to express a fraction instead of a/b, and also use double line space and double dollar sign to center and make things bigger and clear, for example compare: $\sum_{n=1}^\infty n!/n^n\,$ with $$\sum_{n=1}^\infty\frac{n!}{n^n}$$ The first one is with one sign dollar to both sides ...A power series is a type of series with terms involving a variable.
