Find all the first order partial derivatives for the following function.f(x ,y, z) = (sin xy)(cos yz2)
A. 
= (y cos xy)(cos yz2); 
= (x cos xy)(cos yz2); 
= -2(yz sin xy)(sin yz2)
B. 
= (y cos xy)(cosyz2); 
= (x cos xy)(cos yz2) - (z2 sin xy)(sin yz2); 
= -2(yz sin xy)(sin yz2)
C. 
= (y cos xy)(cos yz2); 
= (z2 sin xy)(sin yz2)- (x cos xy)(cos yz2); 
= 2(yz sin xy)(sin yz2)
D. 
= (y cos xy)(cos yz2); 
= (x cos xy)(cos yz2) - (z2 sin xy)(sin yz2); 
= 2(yz sin xy)(sin yz2)
