In the context of Lagrange multipliers, the value of the multiplier λ  represents:

When using the Lagrange multiplier method, the method can find:

Consider the problem of maximizing f(x, y) = x² + y² subject to the constraint x + y = 1. The Lagrange function L(x, y ,λ) is:

In the context of the Lagrange multiplier method, a constraint is typically represented as:

The Lagrange multiplier method is primarily used for handling:

In the method of Lagrange multipliers, if f(x, y) is the function to be optimized and g(x, y) = 0 is the constraint, the system of equations to be solved is given by:

In the Lagrange multiplier method, if the gradients of the objective function and the constraint are not parallel at a point, that point cannot be an optimum.

In economics, the Lagrange multiplier λ is often interpreted as:

In the method of Lagrange multipliers, the critical points are found by:

The Lagrange multiplier method is used to:

In the Lagrange multiplier method, the multiplier λ indicates the sensitivity of the optimal value to changes in the constraint.
