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 \; \text {and} \; h (x,y,z)=0. There are two Lagrange multipliers, λ_1 and λ_2, and the system of equations becomes.Lagrange Multiplier - 2-D Graph.

Advantages and Disadvantages. Although the Lagrange multiplier is a very useful tool, it does come with a large downside: while solving partial derivatives is fairly straightforward, three variables can be bit daunting (and a lot to keep track of) unless you are very comfortable with calculus.
