The constraint is 1 = x 2 + y 2 + z 2, which is the same as 1 = x 2 + y 2 + z 2. The function to maximize is x y z. The two gradient vectors are 2 x, 2 y, 2 z and y z, x z, x y , so the equations to be solved are.

So here's the clever trick: use the Lagrange multiplier equation to substitute ∇f = λ∇g: But the constraint function is always equal to c, so dg 0 /dc = 1. Thus, df 0 /dc = λ 0. That is, the Lagrange multiplier is the rate of change of the optimal value with respect to changes in the constraint.

g (x, y, z) = 2x + 3y - 5z. It is indeed equal to a constant that is ‘1’. Hence we can apply the method. Now the procedure is to solve this equation: ∇f (x, y, z) = λ∇g (x, y, z) where λ is a real number. This gives us 3 equations and the fourth equation is of course our constraint function g (x, y, z).Solve for x, y, z and λ.

Something to consider: Lagrange multipliers work on the principle that both equations are acting in the same direction, but aren't necessarily of the same scale (Lambda being the scalar). To ensure they're in the same direction, we take the Gradient of each (sum of the partial derivatives with respect to each ...

This does not fit with your second or third equation, so you must set y = z = 0; but you can adjust x to match your final equation and thus get candidates for an extreme point with the zero derivative. You find x = ± 1, y = z = 0. You then have the function, with the Lagrnge multiplier built in: x 2 + y 2 + z 2 − 1 ( z 2 + 2 y 2 − z 2 − ...
