∫ sin² x /( 1+ cos x ) dx 

Let's multiply both numerator and denominator by ( 1 - cos x )

= ∫ sin² x • ( 1 - cos x ) / ( 1 + cos x ) • ( 1 - cos x ) dx 

= ∫ sin² x • (1 - cos x ) / ( 1 - cos² x ) dx 

= ∫ sin² x • ( 1 - cos x ) / ( sin² x ) dx         ( 1 - cos² x = sin² x )

= ∫ ( 1 - cos x ) dx         ( sin² x   cancels out )

= ∫ 1• dx - ∫ cos x dx 

= x - sin x + C
