prove $$\sum_{n=2}^{\infty} \frac{1}{n \log n}$$ diverge. I have done this problem using cauchy integral test and condensation test. But i want to do it by comparison test or by limit comparison test . any hint about that .
Thanks in advanced.

How to find $\lim_{h\rightarrow 0}\frac{\sin(ha)}{h}$ without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
