Find all the first order partial derivatives for the following function.f(x, y, z) = cos x sin2 yz
A. 
= sin x sin2 yz; 
= -2z cos x sin yz cos yz; 
= - 2y cos x sin yz cos yz
B. 
= -sin x sin2 yz; 
= z cos x sin yz cos yz; 
= y cos x sin yz cos yz
C. 
= sin x sin2 yz; 
= - cos x sin yz cos yz; 
= -cos x sin yz cos yz
D. 
= -sin x sin2 yz; 
= 2z cos x sin yz cos yz ; 
= 2y cos x sin yz cos yz
