# Gamma Derivative Twice!

Calculus Level 4

$\large \Gamma ^{ \prime \prime }\left( 3 \right) ={ F\gamma }^{ A }+\frac { { \pi }^{ B } }{ C } +D-E\gamma$

The equation above holds true for integers $$A,B,C,D$$ and $$E$$. Find $$A+B+C+D+E+F$$.

Notations:

• $$\Gamma(\cdot)$$ denotes the Gamma function. And $$\Gamma''$$ denotes the second derivative of the Gamma function.

• $$\gamma$$ denote the Euler-Mascheroni constant, $$\gamma \approx 0.5772$$.
