Let f be a function of two variables and suppose that all the first order partial derivatives of f exist and are continuous at all points. Show that for the composite function w=xyf(xz,yz) the following equation holds: x(dw/dx)+y(dw/dy)-z(dw/dz) = 2w

are u comparing the derivative form? for example of w in comparison to x? before i answer the question, because there are many ways to do this, are u in high school or calc 1 university?

I'm expecting it to be difficult. I understand most of the vector geometry stuff. Its the Taylor series stuff and implicit partial differentiation that is getting me.

this is a one slide ppt on partial derivatives that might help u that my prof posted up.

see if that helps, cuz it would be extremily long to write out the proof.
