Find the partial derivative of the dependent variable or function with respect to each of the independent variables.f(x, y) = sin2 (4xy2 - y)
A. 
= 8y2sin (4xy2 - y) cos (4xy2 - y); 
= 2sin (4xy2 - y) cos (4xy2 - y)
B. 
= 8y2sin (4xy2 - y) cos (4xy2 - y); 
= (16xy - 2) sin (4xy2 - y) cos (4xy2 - y)
C. 
= 2sin (4xy2 - y) cos (4xy2 - y); 
= 2sin(4xy2 - y) cos(4xy2 - y)
D. 
= 2sin (4xy2 - y) cos (4xy2 - y); 
= (16x - 2) sin (4xy2 - y) cos (4xy2 - y)
