One of the more common mistakes is to just focus in on the denominator and make a guess based just on that. This will, in turn, make the denominator smaller and so the term will get larger or. In this case the two terms in the denominator are both positive. There are plenty of resources and people who can help you out. Sometimes there is something going on in the numerator that will change the convergence of a series from what the denominator tells us should be happening. If \(c\) is positive and finite this is saying that both of the series terms will behave in generally the same fashion and so we can expect the series themselves to also behave in a similar fashion. The values however are definitely different despite the fact that the terms are the same. Copy link. You write down problems, solutions and notes to go back. Expanded capability of the p-Series Test and the Geometric Series Test. Here is an example of this. The following variant of the comparison test will allow us to determine the convergence of this series. To show that a series (with only positive terms) was divergent we could go through a similar argument and find a new divergent series whose terms are always smaller than the original series. Info. Solution Recall that the nth term test can help us determine whether the series is divergent by checking the limit of a n as n . sites are not optimized for visits from your location. MathBitsNotebook Geometry CCSS Lessons and Practice is a free site for Directions: Carry the full calculator value until rounding the final answer.
