Assignment
Test on Friday covering all of chapter 4. Of course, you must
know the material in chapter 3 as well (rules of differentiation,
etc.) inorder to do chapter four.
Brief review of the lecture
We discussed the quidlines for optimization on page 345. It
is especially important to assign a letter to each variable mentioned
in the problem and to carefully write down the meaning of the
variable. What function is being optimixed? Is it expressible
as a function of a single variable? If not can some of the variables
be solved for and replaced? Don't forget to use one of the tests
(first derivative or second derivative) to prove that the critical
point found is the location of the type of extremum that you're
interested in.
We worked the inventory problem (Example 5) and the Charter
Flight problem (#15) in class.
