The Glaisher–Kinkelin constant is defined by the formula $$A=\displaystyle\lim_{n \rightarrow \infty} \dfrac{(2\pi)^{\frac{n}{2}}n^{\frac{n^2}{2}-\frac{1}{12}}e^{-\frac{3n^2}{4}+\frac{1}{12}}}{G(n+1)}.$$

Theorem
The following formula holds: $$\zeta'(-1)=\dfrac{1}{12}-\log(A),$$ where $\zeta$ denotes the Riemann zeta function, $A$ denotes the Glaisher–Kinkelin constant, and $\log$ denotes the logarithm.
