A. 
= 2sin (8xy2 - y) cos (8xy2 - y); 
= 2sin(8xy2 - y) cos(8xy2 - y)
B. 
= 16y2sin (8xy2 - y) cos (8xy2 - y); 
= 2sin (8xy2 - y) cos (8xy2 - y)
C. 
= 16y2sin (8xy2 - y) cos (8xy2 - y); 
= (32xy - 2) sin (8xy2 - y) cos (8xy2 - y)
D. 
= 2sin (8xy2 - y) cos (8xy2 - y); 
= (32x - 2) sin (8xy2 - y) cos (8xy2 - y)
