Question

partial derivatives fx, fy, and fz for sin(-xyz)+y

Answer 1

A partial derivative is the derivative while assuming all other variables but the one we're dealing with to be constants. Just pretend that for the partial derivative fx that y and z are constants and work from there.

Answer 2

I understand the concept but I'm still having trouble getting to the correct answer for this problem

Answer 3

Well, can you show us what you did? Your step.s

Answer 4

I got fx=cos(-xyz)*-yz fy=cos(-xyz)*-xz+1 fz=cos(-xyz)*-xy I just want to see if they are correct by seeing what someone else gets
