$\frac{ d }{ dx } {\log (\sin^2(2x))} = \frac{ 1 }{ \sin^2(2x) } \frac{ d }{ dx } \sin^2(2x) \\ = \frac{ 1 }{ \sin^2(2x) } \cdot 2\sin (2x) \cdot \frac{ d }{ dx } \sin (2x) \\ = \frac{ 1 }{ \sin^2(2x) } \cdot 2\sin (2x) \cdot \cos (2x) \frac{ d }{ dx } 2x \\ = \frac{ 1 }{ \sin^2(2x) } \cdot 2\sin (2x) \cdot \cos (2x) \cdot 2 \\ = \frac{ 4\cos (2x) }{ \sin(2x) } \\ = 4 \tan^{-1}(2x)$
