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.This Demonstration gives a geometric representation of the method of Lagrange multipliers. The initial view shows the red point iteratively moving toward a minimum of a specified function. At each iteration the point takes a small step in the direction shown by the red arrow that causes the greatest reduction in the value of the function i.e. the direction of steepest descent.
