I f t a n ( π 4 + y 2 ) = t a n 3 ( π 4 + x 2 ) t h e n s i n x ( 3 + s i n 2 x 1 + 3 s i n 2 x ) = ? If\quad tan\left( \frac { \pi }{ 4 } +\frac { y }{ 2 } \right) ={ tan }^{ 3 }\left( \frac { \pi }{ 4 } +\frac { x }{ 2 } \right) \quad then\quad sin\quad x\left( \frac { 3+{ sin }^{ 2 }x }{ 1+{ 3sin }^{ 2 }x } \right) =?

sin y 0 None of them No Solution sin x/y s i n 2 x { sin }^{ 2 }x 1 sin x
