# What's happening to the limits?

Calculus Level 5

$\large \int _{ 0 }^{ \pi }{ { x }^{ 3 } } \left( { \ln}{ }\left| 2\sin { \dfrac { x }{ 2 } } \right| \right) ^2 \, dx=\dfrac { A }{ B } { \pi }^{ C }\zeta ( D ) -\dfrac { E }{ F } \zeta ( G )$

The above equation holds true for positive integers $$A$$, $$B$$, $$C$$, $$D$$, $$E$$, $$F$$ and $$G$$, where $$\gcd(A,B) = \gcd(E,F) = 1$$.

Find the minimum value of $$A+B+C+D+E+F+G$$.
