In this video we go over how to use Lagrange Multipliers to find the absolute maximum and absolute minimum of a function of three variables given a constrain. Lagrange Multiplier Example. The method of Lagrange multipliers, which is named after the mathematician Joseph-Louis Lagrange, is a technique for locating the local maxima and minima of a function that is subject to equality constraints. Lagrange Multipliers Lagrange Multipliers Suppose that we have a function f (x,y) that we want to maximize in the restricted domain g (x,y) = c for some constant c. Then we can look at the level curves of f and seek the largest level curve that intersects the curve g (x,y) = c. It is not hard to see that these curves will be tangent.
