Summation ratio test
WebIf r = 1, the root test is inconclusive, and the series may converge or diverge. The root test is stronger than the ratio test: whenever the ratio test determines the convergence or … In mathematics, the ratio test is a test (or "criterion") for the convergence of a series 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.

The ratio test says that the for the series ∑an, we can make a determination about its convergence by taking L = lim a→ ∞ ∣∣ ∣ an+1 an ∣∣ ∣. Examine the value of L: If L > 1, then ∑an is divergent. If L = 1, then the test is inconclusive. If L < 1, then ∑an is (absolutely) convergent. kate farms standard 1.0 chocolateWebIn mathematics, a series is the sum of the terms of an infinite sequence of numbers. More precisely, an infinite sequence (,,, …) defines a series S that is denoted = + + + = =. The n th partial sum S n is the sum of the first n terms of the sequence; that is, = =.
