[1] Determine the absolute maximum and absolute minimum values of f ( x, y) = ( x 1) 2 + ( y 2) 2 subject to the constraint that . In the case of an objective function with three variables and a single constraint function, it is possible to use the method of Lagrange multipliers to solve an optimization problem as well. In mathematical optimization, the method of Lagrange multipliers is a strategy for finding the local maxima and minima of a function subject to equality constraints (i.e., subject to the condition that one or more equations have to be satisfied exactly by the chosen values of the variables ). Determine the objective function \(f(x,y)\) and the constraint function \(g(x,y).\) Does the optimization problem involve maximizing or minimizing the objective function? Let f ( x, y) and g ( x, y) be functions with continuous partial derivatives of all orders, and suppose that c is a scalar constant such that g ( x, y) 0 for all ( x, y) that satisfy the equation g ( x, y) = c. Then to solve the constrained optimization problem. Lagrange multiplier calculator finds the global maxima & minima of functions.
