Timeline for Is this combination of generalized polygamma and dilogarithm actually zero? $\Im\;\psi^{(-2)}(1+i)+\frac1{4\pi}\text{Li}_2(e^{-2\pi})-\log\sqrt{2\pi}+\frac{5\pi}{24}+\frac12$

| Jan 6, 2015 at 19:00 | comment | added | Gerald Edgar | Maple's and Mathematica's functions $\psi^{(-2)}$ both have second derivative $\Gamma'(z)/\Gamma(z)$, so they differ only by some $az+b$ function. | |
| Jan 6, 2015 at 18:12 | comment | added | Vladimir Reshetnikov | BTW, Maple has different definitions for $\psi^{(-2)}(z)$ and $\psi^{(-1)}(z)$ than Mathematica (and Wolfram Alpha). | |
