WebApr 17, 2024 · In this section we will discuss using the Root Test to determine if an infinite series converges absolutely or diverges. The Root Test can be used on any series, but … WebIf L < 1, then ∑ a n converges absolutely. If L > 1, or the limit goes to ∞, then ∑ a n diverges. If L = 1 or if L does not exist, then this test is inconclusive, and we must do more work.

The root test states that: if C &lt; 1 then the series converges absolutely, if C &gt; 1 then the series diverges, if C = 1 and the limit approaches strictly from above then the series diverges, otherwise the test is inconclusive (the series may diverge, converge absolutely or converge conditionally ). See more In mathematics, the root test is a criterion for the convergence (a convergence test) of an infinite series. It depends on the quantity where See more The root test was developed first by Augustin-Louis Cauchy who published it in his textbook Cours d'analyse (1821). Thus, it is sometimes known as the Cauchy root test or Cauchy's radical test.
