18 paź 2018 · Use the ratio test to determine absolute convergence of a series. Use the root test to determine absolute convergence of a series. Describe a strategy for testing the convergence of a given series. In this section, we prove the last two series convergence tests: the ratio test and the root test.
Ratio Test – Definition, Conditions, and Examples on Series. The ratio test is an important method to learn when analyzing different infinite series. It’s one of the first tests used when assessing the convergence or divergence of a given series – especially the Taylor series.
In mathematics, the ratio test is a test (or "criterion") for the convergence of a series ∑ n = 1 ∞ a n , {\displaystyle \sum _{n=1}^{\infty }a_{n},} where each term is a real or complex number and a n is nonzero when n is large.

Using the ratio test Example Determine whether the series X∞ n=1 ln(n) n converges or not. Solution: We start with the ratio test, since a n = ln(n) n > 0. Then, a n+1 a n = ln(n +1) (n +1) n ln(n) = n (n +1) ln(n +1) ln(n) → 1 Since ρ = 1, the ratio test is inconclusive. Direct comparison test: a n = ln(n) n > 1 n implies that X ln(n) n ...
2 lip 2021 · The following advanced exercises use a generalized ratio test to determine convergence of some series that arise in particular applications when tests in this chapter, including the ratio and root test, are not powerful enough to determine their convergence.
