comment How do I evaluate this:$\sum_{n=1}^{\infty}\frac{1}{n²}(e^x −1 −\frac{x}{1!} −\frac{x²}{2!}−\cdots\frac{x^n}{n!})$?
@zeraouliarafik: Nitin's answer still works out basically the same if you have $n^2$ instead of $\frac{1}{n^2}$. If you use the integral form of the remainder, you can even get a closed form for the sum...

Make that $\max(1,e^x)$ and you'll be fine.
