I'll use Maple syntax for mathematical notation on this page.
All numbers indicate sections from Multivariable Calculus by Ostebee/Zorn.

For March 3

Section 2.4 The gradient and directional derivatives
  • To read : All
  • Be sure to understand : The definition of the gradient

Reading Questions : Suppose (1,2) is a point in the domain of the fuction f(x,y).

  1. What type of quantity is the gradient of f at (1,2)?
  2. How is the gradient at (1,2) related to the level curve through (1,2)?

For March 5

Section 2.4 The gradient and directional derivatives (continued) Reread the section, but no Reading Questions for today.

For March 7

Section 2.5 Local Linearity: theory of the derivative
  • To read : All
  • Be sure to understand : Example 1, the definition of the total derivative

Reading Question:

    What is the point of Example 1?

For March 10

Section 2.7 Maxima, Minima, and Quadratic Approximation
  • To read : Through Example 5
  • Be sure to understand : Examples 2 and 3

Reading Questions:

  1. If the partials fx and fy exist everywhere, at what points (x0, y0) can f have a local max or a local min?
  2. Why does the term "saddle point" make sense?

For March 12 & 14

Work on Project 2 - No reading assignment.

For March 17, 19, & 21

Spring Break, so obviously no reading assignment.

For March 24

Section 2.8 The Chain Rule
  • To read : All
  • Be sure to understand : The definition of the derivative matrix, the statement of the Chain Rule (Theorem 4), and Example 5.

Reading Questions:

  1. If f:R5 -> R3, how many rows does the derivative matrix of f contain? How many columns?
  2. If f:R3 -> R4 and g:R4 -> R5, what will the dimensions of the derivative matrix of g o f be?

For March 26

Section 3.1 Multiple Integrals and Approximating Sums
  • To read : All
  • Be sure to understand : The section Approximating Sums on page 173 and the definition of the double integral as a limit on page 175

Reading Question:

  1. If f(x,y) is a function of two variables, what does R f(x,y) dA measure?
  2. For any region R in the plane, what does R 1 dA measure?

For March 28

Section 3.2 Calculating Integrals by Iteration
  • To read : All
  • Be sure to understand : The section "Iteration: why it works"

Reading Question:

    What is the advantage of calculating double integrals by iteration?

For March 31

Section 3.2 Calculating Integrals by Iteration
Reread the section, especially the proof of Theorem 1 but there are no reading questions for today.
