If x(n)=xR(n)+jxI(n) is a complex sequence whose Fourier transform is given as X( )=XR( )+jXI( ), then what is the value of xI(n)?

( int_0^{2 } )[X R ( ) sin n+ X I ( ) cos n] d

( frac{1}{2 } int_0^{2 } )[XR( ) sin n+ XI( ) cos n] d

( int_0^{2 } )[XR( ) sin n+ XI( ) cos n] d

( frac{1}{2 } int_0^{2 } )[XR( ) sin n XI( ) cos n] d
