(delw)/(delx) = x/sqrt(x^2 y^2 z^2) (delw)/(dely) = y/sqrt(x^2 y^2 z^2) (delw)/(delz) = z/sqrt(x^2 y^2 z^2) Since you're dealing with a multivariable function, you must treat x, y, and z as independent variables and calculate the partial derivative of w, your dependent variable, with respect to x, y, and z There are two possible pathways here implicit differentiation or partial differentiation For implicit differentiation, we have both variables ( x and y) into the derivative at once, while for partial differentiation we work with each one separately Implicitly differetiating, then, we must resort to chain rule, by naming u = x2 y2 and, therefore, f x ( x 0, y 0) ( x − x 0) f y ( x 0, y 0) ( y − y 0) f ( x 0, y 0) is the z value of the point on the plane above ( x, y) Equation 1431 says that the z value of a point on the surface is equal to the z value of a point on the plane plus a "little bit,'' namely ϵ 1 Δ x ϵ 2 Δ y
