Method of Lagrange Multipliers. Candidates for the absolute maximum and minimum of f ( x, y) subject to the constraint g ( x, y) = 0 are the points on g ( x, y) = 0 where the gradients of f ( x, y) and g ( x, y) are parallel. To solve for these points symbolically, we find all x, y, λ such that. ∇ f ( x, y) = λ ∇ g ( x, y) and. From instruct.math.lsa.umich.edu

The first, λ = 0 λ = 0 is not possible since if this was the case equation (1) (1) would reduce to. y z = 0 ⇒ y = 0 or z = 0 y z = 0 ⇒ y = 0 or z = 0. Since we are talking about the dimensions of a box neither of these are possible so we can discount λ = 0 λ = 0. This leaves the second possibility. x z = y z x z = y z. From tutorial.math.lamar.edu
