SUMMARY

The discussion focuses on investigating the convergence of a specific function using the ratio test. Participants recommend applying the ratio test to derive an integral from 1/(n+1) to 1/n, aiming to demonstrate that the limit of this integral approaches a value less than 1 as n approaches infinity. The integral in question is expressed as \lim_{n\to \infty} \frac{ \int^{1/{n+1}}_0 \frac{x^{1/4}}{1+x^2} dx}{ \int^{1/{n}}_0 \frac{x^{1/4}}{1+x^2} dx}. The discussion also highlights a potential issue with LaTeX formatting in the original post.

I would recommend using the "ratio test". That will lead to an integral from 1/(n+1) to 1/n and you need to show that the limit of that integral, as n goes to infinity, is less than 1.
 
[tex]\lim_{n\to \infty} \frac{ \int^{1/{n+1}}_0 \frac{x^{1/4}}{1+x^2} dx}{ \int^{1/{n}}_0 \frac{x^{1/4}}{1+x^2} dx}[/tex].

I'm not sure how that gives an integral from 1/(n+1) to 1/n =S

EDIT: Dont know what's wrong with the latex.
