Math 127(3) - Warren D. Smith - Homework #5 - due Tues 4 Mar 2003
------------------------------------------------------------------
Finish reading ch 15.
You should understand gradients, directional derivatives,
and how to find them; how to optimize a function, how to
distinguish maxima, minima, and saddle points (for smooth
functions in generic situations) for functions of 2 variables by using 2nd partial
derivative info, and how to solve CONSTRAINED optimization problems
using LAGRANGE MULTIPLIER technique.

Then can start reading ch 16.

Do these exercises in section 15.10 (page 1028 my book) #4, #16.

In section 15.8 (page 1013 my book) #6, #9, #18.

In section 15.2 (Page 962 my book) #18.
[see defn 15.2.2 in book if forget what a directional derivative is...]
