\int\sqrt { { \cos x - \cos ^ { 3 } x } /{ 1 - \cos ^ { 3 } x } } d x =

Correct Answer is : −23sin−1(cos32x)+c

- { 2 }/ { 3 } \sin ^ { - 1 } ( \cos ^ { 3 / 2 } x ) + c

{ 1 }/ { 3 } \cos ^ { - 1 } ( \cos ^ { 3 / 2 } x ) + c

- { 3 } /{ 2 } \sin ^ { - 1 } ( \cos ^ { 3 / 2 } x ) + c

{ 3 }/ { 2 } \cos ^ { - 1 } ( \cos ^ { 3 / 2 } x ) + c
