Homework Statement


Prove that sum(n=0 to infty, (zeta(it))^(n)) equals zero when the variable (it) is the imaginary part of the nontrivial zeros of the Riemann zeta function that have real part 1/2. For example, it=14.134i. Note: n represents the nth derivative of the zeta function.

The Attempt at a Solution


I tried to approach this problem by expanding using a Euler-MacLaurin expansion, but failed because I obtained the original equation. Any help would be VERY much appreciated.

I really need help in the next hour or so; my proof fell apart at the last minute.
 
I changed the format to make the problem easier to read.

Prove that \sum_{n=0}^{\infty} f^n(it) equals 0 when it is equal to the imaginary part of the zeros of the Riemann Zeta function that have real part 1/2, for example, it=14.134i. Note: f^n(it) is the nth derivative of the Riemann Zeta function
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
