# Engineering Analysis/Minimization

Before reading this chapter, the student should know what minimization is, and how to minimize a function. Students should also know partial differentiation, and how to solve systems of equations. |

## Khun-Tucker Theorem edit

The Khun-Tucker Theorem is a method for minimizing a function f(x) under the constraint g(x). We can define the theorem as follows:

Where Λ is the *lagrangian vector*, and < , > denotes the **scalar product** operation. We will discuss scalar products more later. If we differentiate this equation with respect to x first, and then with respect to Λ, we get the following two equations:

We have the final result:
