Is this combination of generalized polygamma and dilogarithm actually zero? $\Im\;\psi^{(-2)...

The following identities hold for all real $x>0$. Your equality is the second identity at $x=1$. $$ -x + \frac{\pi}{12}(6x^2-1) + x\log{x} - x \log(2\pi) + 2\Im{\psi^{(-2)}(ix)} + \frac{1}{2\pi}\text …

Are all zeros of $\Gamma(s) \pm \Gamma(1-s)$ on a line with real part = $\frac12$ ?

I would like to expand on Guild of Pepperers's answer by noting that the zeros are essentially uniformly spaced and may easily be approximated to a high degree of accuracy. Using Stirling approximati …
