Help with finding zeros
Posted:
Sep 13, 2010 9:32 AM


I could use a little help trying to solve the following engineering problem (no, I am not a student looking for homework help!)
I need to find the values of w which cause the following summation to go to zero
sum (n = 1 to N) of exp(i*w*ln(n))
where i is the usual sqrt(1)
For a given N, there are infintely many solutions due to the periodicity of exp(i ...) How do I find these solutions?
Thanks for any pointers.
