I need to know what the function $\sum \limits_{n=1}^{\infty}\frac{1}{n3^n}$ represents evaluated at a particular point.
For example if the series given was $\sum \limits_{n=0}^{\infty}\frac{3^n}{n!}$ the answer would be $e^x$ evaluated at $3$.
Yes, this is homework, but I'm not looking for any handouts, any help would be greatly appreciated.
