Discussion Overview

The discussion revolves around the convergence of a specific series, with participants evaluating the application of the ratio test and the Cauchy root test. The focus is on verifying the convergence of the series and the methods used to analyze it.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant believes the series converges based on the ratio test.
  • Another participant references Wolfram Alpha, which also indicates convergence.
  • A different participant expresses uncertainty about the ratio test, stating it yields an inconclusive result (equal to 1) and seeks confirmation from others.
  • One participant suggests that the series converges using the Cauchy root test instead of the ratio test.
  • Another participant agrees with the use of the root test, noting that the ratio test can be complicated without specific limits.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the convergence of the series, as there are competing views regarding the effectiveness of the ratio test versus the Cauchy root test.

Contextual Notes

Some participants express uncertainty about the application of the ratio test and its results, indicating potential limitations in their understanding or the methods used.

What's wrong? Wolfram says it is convergent too.
 
Sorry, i just want to check the work. I am having some trouble convincing myself that it is correct. I keep getting that the ratio test is inconclusive (=1) so i need to see someone else work the problem.
 
I do not know about the ratio test but the series surely converges by the Cauchy root test.
 
I've got it, but it's messy with the ratio test unless you imply some limits. Root test FTW!
