Extremum of a Function: Constraints

This lecture covers the concept of extremum of a function under constraints, focusing on the conditions where a function admits one. The instructor explains how to find candidate points and extremums of a function in practice, considering constraints and projections. The lecture also discusses the process of moving around points based on projections and tangent planes, emphasizing the importance of linear independence and constraint satisfaction. Practical examples and techniques are provided to illustrate the application of these concepts.
