$\displaystyle n$

$\displaystyle \sum e^\frac{i}{n}(\frac{1}{n})$

$\displaystyle i = 1$

$\displaystyle \frac{1}{n}[ e^\frac{1}{n} + e^\frac{2}{n} + e^\frac{3}{n} +.....+ e^\frac{n}{n} ]$

Did i compute wrongly ? I find it a bit weird. I can't proceed further on combining the bracket terms.

Thanks.
