Best ResponseYou've already chosen the best response.0the answer should be z= f(x,y). so i am asking what f(x,y) is

Best ResponseYou've already chosen the best response.0oh ok, i got the gradient vector, then plug in the point (1,1,1) to df/dx to get the answer?

amistre64

Best ResponseYou've already chosen the best response.0dot product that with the vecotr that is the point...<1,1,1>

Best ResponseYou've already chosen the best response.0doesnt the gradient vector give <df/dx, df/dy,df/dz>... in that case we can simply do df/dx / df/dz???

Best ResponseYou've already chosen the best response.0yes, get the gradient, and plug in the x,y and z valuse of the point into the gradient and divide df/dx by df/dz to get dz/dx right?
