Nov 17, 2022 · The method of Lagrange multipliers can be applied to problems with more than one constraint. In this case the objective function, w is a function of three variables: w = f(x, y, z) and it is subject to two constraints: g(x, y, z) = 0 and h(x, y, z) = 0. There are two Lagrange multipliers, λ1 and λ2, and the system of equations becomes.
