    Step 1: Introduce a new variable λ. , and define a new function L. as follows: L ( x, y, …, λ) = f ( x, y, …) − λ ( g ( x, y, …) − c) This function L. is called the "Lagrangian", and the new variable λ. is referred to as a "Lagrange multiplier" Step 2: Set the gradient of L. equal to the zero vector. ∇ L ( x, y, …, λ) = 0 ← Zero vector.

    Example \(\PageIndex{1}\): Using Lagrange Multipliers. Use the method of Lagrange multipliers to find the minimum value of \(f(x,y)=x^2+4y^2−2x+8y\) subject to the constraint \(x+2y=7.\) Solution. Let’s follow the problem-solving strategy: 1. The objective function is \(f(x,y)=x^2+4y^2−2x+8y.\)
