#### When does a power series converge in the ratio test?

By the ratio test, the power series converges if 0 ≤ r<1, or |x− c| <R, and diverges if 1 <r≤ ∞, or |x−c| >R, which proves the result. The root test gives an expression for the radius of convergence of a general power series.

#### When to use ratio test for a series?

We recommend you to use this series test if your series appear to have factorials or powers. The definition of the ratio test is the following: . Then we say that: If r < 1, then the series is convergent. A converging series means that the infinite series has a finite sum. If r > 1 (including infinity), then the series is divergent.

#### What is the purpose of the ratio 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.

#### When is the ratio of a series nonzero?

In mathematics, the ratio test is a test 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 an is nonzero when n is large. 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.
