Let $$f\left( x \right) =\cfrac { 2\sin ^{ 2 }{ x } -1 }{ \cos { x

}  } +\cfrac { \cos { x } \left( 2\sin { x } +1 \right)  }{ 1+\sin { x

}  } $$ then
$$\int { { e }^{ x }\left( f\left( x \right) +f'\left( x \right)  \right) dx } $$ (where c is the constant of integration)


ANSWER

$${ e }^{ x }\tan { x } +c$$
