I am trying to find or get a numerical approximation of $$ \sum_{\rho \text{ non-trivial zeros of } \zeta} \frac{1}{\rho} $$ In [The Riemann Hypothesis: Arithmetic and Geometry](http://www.math.lsa.umich.edu/~lagarias/doc/mt-holyoke-rev.pdf) Lagarias gives the identity: $$\hat{\zeta}(s) := \pi^{-\frac{s}{2}} \Gamma(\frac{s}{2})\zeta(s)$$ $$ \frac{\hat{\zeta}^\prime(s)} {\hat{\zeta}(s)} = \frac{d}{ds} [ \log \hat{\zeta}(s) ] = -\frac{1}{s} - \frac{1}{s-1} + {\sum_{\rho \text{ zeros of } \zeta }}^\prime \frac{1}{s-\rho} \qquad(1)$$ where the prime indicates the zeros must be summed in pairs $\rho,1-\rho$ >Q1 Does the last sentence mean that the sum is over the non-trivial zeros? Maple gives: $$\lim_{s \to 0} {\sum_{\rho \text{ zeros of } \zeta }}^\prime \frac{1}{s-\rho} = -\gamma + \frac{1}{2} \log\left(\pi\right) + \log\left(2\right) - 1$$ If the above result is correct, is it true that: $$ \sum_{\rho \text{ non-trivial zeros of } \zeta} \frac{1}{\rho} = \gamma - \frac{1}{2} \log\left(\pi\right) - \log\left(2\right) + 1 $$ This is almost sure wrong because zeros on the critical line are conjugates and RH is equivalent to: $$ \sum_{\rho} \frac{1}{|\rho|^2} = \text{certain constant}$$
