Homework Help Overview

The discussion revolves around proving the existence of a limit for the sequence {X_n} using the Cauchy criterion. The sequence is defined as {X_n} = (10/1)(11/3)...((n+9)/(2n-1)).

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to apply the Cauchy criterion but questions the correctness of their approach. Participants raise questions about the dependency of N on ε and the choice of p in their reasoning.

Discussion Status

The discussion is ongoing, with participants questioning the assumptions made by the original poster regarding the choice of p and the fixed nature of N. There is no explicit consensus, but participants are engaging in clarifying the reasoning behind the choices made.

Contextual Notes

Participants are discussing the implications of their choices in the context of the Cauchy criterion, particularly focusing on the definitions and assumptions related to the sequence and its limit.

Your N is not fixed; it should depend on [tex]\varepsilon[/tex] only.

What's s?
Why did you pick p = 1?

give me a reason y i can't pick p=1

and bout the Sn
Sn= sum of the series from a1 to an

.
 
No one has to give you a reason why you can't pick p= 1. You are the one who is doing this. Please answer the question- why DID you pick p= 1?
