(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]

\sum_{n = 2}^{\infty} \frac{1}{n*ln(n)}

[/tex]

I have to find whether the series absolute converge, conditionally converge or diverge?

2. The attempt at a solution

I used the ratio test.

so, lim(n to infinity) [n*ln(n)]/[(n+1)*ln(n+1)]

since ln (n+1) will be greater than ln (n) and n+1 will be greater than n, the whole denominator will be greater than the numerator so when i take the limit, the value must be less than 1.

but i think i have cancel n or ln(n) to show that the whole limit is really less than 1 to converge.

help!!!!

i m sorry . i dun know how to use the latex code..
