In mathematics , a series is the sum of the terms of an infinite sequence of numbers. The n th partial sum S n is the sum of the first n terms of the sequence; that is,.

In the previous section we saw how to relate a series to an improper integral to determine the convergence of a series.

In mathematics , the ratio test is a test or "criterion" for the convergence of a series. The test was first published by Jean le Rond d'Alembert and is sometimes known as d'Alembert's ratio test or as the Cauchy ratio test. The usual form of the test makes use of the limit. It is possible to make the ratio test applicable to certain cases where the limit L fails to exist, if limit superior and limit inferior are used. More specifically, let. Then the ratio test states that: [2] [3].

So the original ratio test is a weaker version of the refined one. In such cases, more refined tests are required to determine convergence or divergence. We can then show that the series converges absolutely by showing that its terms will eventually become less than those of a certain convergent geometric series.

Hence the series diverges. As seen in the previous example, the ratio test may be inconclusive when the limit of the ratio is 1. Extensions to the ratio test, however, sometimes allows one to deal with this case. These tests also may be applied to any series with a finite number of negative terms. Any such series may be written as:.

In fact, no convergence test can fully describe the convergence properties of the series. Convergence tests essentially use the comparison test on some particular family of a n , and fail for sequences which converge or diverge more slowly. Augustus De Morgan proposed a hierarchy of ratio-type tests [4] [9]. This term can replace the former term in the definition of the test parameters and the conclusions drawn will remain the same.

Accordingly, there will be no distinction drawn between references which use one or the other form of the test parameter. This extension is due to Joseph Ludwig Raabe. The series will: [7] [10] [9]. For the limit version, [12] the series will:.

When the above limit does not exist, it may be possible to use limits superior and inferior. The proof of the other half is entirely analogous, with most of the inequalities simply reversed. Bertrand's test [4] [10] asserts that the series will:. This extension probably appeared at the first time by Margaret Martin in.

The empty sum is assumed to be 0. The series. For applications of Extended Bertrand's test see birth—death process. This extension is due to Carl Friedrich Gauss. Kummer's test states that the series will: [5] [6] [10] [11].

For the limit version, the series will: [16] [7] [9]. All of the tests in De Morgan's hierarchy except Gauss's test can easily be seen as special cases of Kummer's test: [4]. Therefore, the limit. This implies that the positive telescoping series. If the above limits do not exist, it may be possible to use the limits superior and inferior. This test is a direct extension of the second ratio test.

8.4: Convergence Tests - Comparison Test

Convergence tests are used to find the convergence of series or power series. There are many tests for convergence, but in this article we are going to focus on the ratio test. Ratio test is one of the tests used to determine the convergence or divergence of infinite series. You can even use the ratio test to find the radius and interval of convergence of power series! Many students have problems of which test to use when trying to find whether the series converges or diverges. We recommend you to use this series test if your series appear to have factorials or powers. Then we say that:.

Осколки посыпались вниз и попали ему в шею. Беккер рванулся влево, в другую улочку. Он слышал собственный крик о помощи, но, кроме стука ботинок сзади и учащенного дыхания, утренняя тишина не нарушалась ничем. Беккер почувствовал жжение в боку. Наверное, за ним тянется красный след на белых камнях.

С каждым завыванием сирены слова Хейла эхом отдавались в ее мозгу: Я сожалею о Дэвиде Беккере. Сьюзан казалось, что она сходит с ума. Она уже готова была выскочить из комнаты, когда Стратмор наконец повернул рубильник и вырубил электропитание. В одно мгновение в шифровалке установилась полная тишина.

    We have seen that the integral test allows us to determine the convergence or divergence of a series by comparing it to a related improper integral.
