We introduce a new variable called a Lagrange multiplier (or Lagrange undetermined multiplier) and study the Lagrange function (or Lagrangian or Lagrangian expression) defined by L ( x , y , λ ) = f ( x , y ) + λ ⋅ g ( x , y ) , {\displaystyle {\mathcal {L}}(x,y,\lambda )=f(x,y)+\lambda \cdot g(x,y),}
Apr 17, 2023 · Solve the following system of equations. ∇f(x, y, z) = λ ∇g(x, y, z) g(x, y, z) = k. Plug in all solutions, (x, y, z) , from the first step into f(x, y, z) and identify the minimum and maximum values, provided they exist and ∇g ≠ →0. at the point. The constant, λ, is called the Lagrange Multiplier.
Suppose \(1\) unit of labor costs \($40\) and \(1\) unit of capital costs \($50\). Use the method of Lagrange multipliers to find the maximum value of \(f(x,y)=2.5x^{0.45}y^{0.55}\) subject to a budgetary constraint of \($500,000\) per year. Hint. Use the problem-solving strategy for the method of Lagrange multipliers. Answer
The method of Lagrange multipliers is a technique in mathematics to find the local maxima or minima of a function f (x_1,x_2,\ldots,x_n) f (x1,x2,…,xn) subject to constraints g_i (x_1,x_2,\ldots,x_n)=0 gi(x1,x2,…,xn) = 0.
