Camp Test solutions

Unread post by nafistiham » Mon Apr 09, 2012 8:53 pm

Camp is over.So I suggest if we could discuss the solutions of the problem sets.
\[\sum_{k=0}^{n-1}e^{\frac{2 \pi i k}{n}}=0\]
Using $L^AT_EX$ and following the rules of the forum are very easy but really important, too.Please co-operate.

হুম, আমি চেষ্টা করি
Camp Test-1 এর ১ নং এর সমাধান আমার আসছে $n=2k$ সকল $k\in\mathbb{N}$ এর জন্য। :(
আসল উত্তরটা কি ???

The problem has cyclic terms, not symmetric (the reason you can not WLOG let $a \geq b \geq c$), and thus I would like to see your solution.

Use $L^AT_EX$, It makes our work a lot easier!

Should I post my solution sheets (PDF)? Or should the problems be discussed?
