A 22 B 24 (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 When you differentiate with respect to x, you treat y and z asLagrange Multipliers Minimum of f(x, y, z) = x^2 y^2 z^2 subject to x y z 9 = 0
