How is the ratio test used to determine a series?
Using the Ratio Test to Determine Whether a Series Converges. The ratio test looks at the ratio of a general term of a series to the immediately preceding term. The ratio test works by looking only at the nature of the series you’re trying to figure out (as opposed to the tests which compare the test you’re investigating to a known,...
How to do the ratio test in calculus?
Ratio Test 1 if L 1 L > 1 the series is divergent. 3 if L = 1 L = 1 the series may be divergent, conditionally convergent, or absolutely convergent.
Which is true in the case of the ratio test?
if L = 1 L = 1 the series may be divergent, conditionally convergent, or absolutely convergent. A proof of this test is at the end of the section. Notice that in the case of L = 1 L = 1 the ratio test is pretty much worthless and we would need to resort to a different test to determine the convergence of the series.
When do you need to use ratio test?
If, in the limit, this ratio is less than 1, the series converges; if it’s more than 1 (this includes infinity), the series diverges; and if it equals 1, you learn nothing, and must try a different test. The ratio test works especially well with series involving factorials such as n! or where n is in the power, like

Both the comparison test and the limit compare test have A major drawback; namely, to use those tests to infer some series we have to atomic number 4 able to every bit powerful and usable as the ratio test is, in that location are certain examples that are indeed nasty that something even stronger is required to clear them.

The theorem as wel leads to letter a very important notice about when letter a series must wealthy person a term that grows at to the lowest degree exponentially in lodg for the ratio test to rich person a chance to be conclusive!
