Lesson Summary:

The lesson covers various examples of applied optimization problems. The problems involve finding the maximum or minimum value of a given objective function, subject to a constraint or set of constraints. The problems are solved using calculus techniques, such as finding critical numbers, determining concavity, and using optimization formulas. The examples include finding the dimensions of a rectangle inscribed in a parabolic region, finding the dimensions of an aquarium with minimal surface area, finding the height and radius of a cone that can contain a sphere with minimal volume, and finding the point on a curve closest to the origin.

Lesson Description:

Several example problems of applied optimization.

This video is a collection of five good applied optimization problems. These problems use ideas and methods we have learned, but they are applied to new situations and word problems. These problems take some really in-depth reasoning, and they are quite difficult and involved. However, they are also very useful and potentially have real-world implications, such as minimizing the construction material for a box or aquarium, minimizing the construction material for a can, and minimizing the volume of a cone.
