Instructor information, including contact information. My office hours are Mon 12:30-1:00, Wed 12:00-1:00, Fri 11:30-3:00. I will be in AMB 110 (my office) or AMB 137 (the MAP room).

pdf of the Syllabus. Here are the math department policies and the university policies that are technically part of the syllabus.

Here is an Introduction to WeBWorK.
You probably won't need this if you have used WeBWorK in a previous class.

**Wednesday, May 2**: Mathematica Notebook for doing the integral in Set 17.3, Problem 3.

**Wednesday, April 25**: Plausibility argument for Green's Theorem:
page 1, page 2, page 3.

**Tuesday, April 24**: Parametrization of a cylinder using DPGraph. Here's the surface from problem 14, with z = 36 - (x^2 + y^2), above the disk of radius 6 in the z = 0 plane.

**Monday, April 16**: Plot of Magnetic Field from current in a wire along the z-axis using DPGraph.

**Friday, April 13:**
Mathematica notebook on divergence and "curl"
of 2-dimensional linear vector fields F(x,y) = (ax + by, cx + dy).

vortex behind an airplane wing.

**Wednesday, April 11**: Plot a 2-dimensional vector field with
DPGraph or
Mathematica. You can also search the web for programs. Note that the DPGraph file does not scale the vectors. Most other vector field plotters scale the vectors.

**Monday, April 9**: Mathematica notebook ChangeOfVariables.nb.

**Friday, March 2**: Here are pictures of the "proof" that mixed partial derivatives are equal I did in class a while ago:
page 1 and page 2.

I finished problem 4 in set 14.6 after class ended and took these pictures of the solution: part 1 and part 2.
This uses the notation for derivatives and the chain rule found in the notes on multi-variable
calculus I put in our BbLearn shell.

**Wednesday, Feb. 28**: Mathematica Notebooks showing graph, contour plot and gradient vector field of functions of 2 variables:
A simple notebook from class, and a more fancy notebook, gradientsExtended.nb.

**Wednesday, Feb. 21**: DPGraph figures showing f(x,y) = x*y/(x^{2} + y^{2}) has no limit at (0, 0) and
g(x,y) = x*y/sqrt(x^{2} + y^{2}) → 0 as (0,0) → (0,0).
The squeeze theorem proves this since -sqrt(x^{2} + y^{2}) ≤ g(x,y) ≤ sqrt(x^{2} + y^{2}) for all (x, y) ≠ (0,0)
and ± sqrt(x^{2} + y^{2}) → 0 as (x, y) → (0, 0).

**Monday, Feb. 19**: This Mathematica notebook shows the level surface in Set 14.1, problem 12.
You can see this on a computer in the Math building, or any computer with Mathematica.
See this site about Mathematica at NAU. You can get Mathematica for your own computer!

**Friday, Feb. 16**: I used this mathematica notebook, quadraticSurfaces.nb to draw the figures for problem 4. In problem 5, many people
had difficulty finding theta, so I wrote this algorithm.

**Friday, Feb. 9**: My office hours end early today. They are 11:30 - 12:30.

Here are two ways to graph 3D curves on the computer. They may help with Problem 7 in set 13.2. They plot a helix with Mahtematica: helix.nb,
helix2.nb and
DPGraph:helix.dpg and helixAndTangentLine.dpg.

Here are some DPGraphs of the trefoil knot:
trefoil.dpg,
trefoilTube.dpg,
trefoilAndTorus.dpg,
trefoilAndTorusTube.dpg

**Friday, Feb. 2**: My office hours end early today. They are 11:30 - 1:00.

You might want to go to my web page about the DPGraph program. It is an awesome program for 3D visualization, but it only works for windows machines (or emulators).
**Extra Credit Opportunity!** Install DP Graph on your laptop. Worth 4 class points if you have a windows machine and 10 points if you have a Mac.
To claim your points, show me your laptop running DPGraph.

**Section 12.1**: The answer to my version of WeBWorK problem 10 in set 12.1 is
**x** = 1 **a** + 1.7 **b**. (So I type 1 and 1.7 into the two blanks.) This figure shows the vectors.
Here is a Mathemetica notebook to allow arbitrary linear combinations of
**a** and **b**.

This is a great webcast introducing you to
*Mathematica*.

You can get extra credit for our course from points earned in the Problem of the Week. You can get up to 3 class points per week. I will multiply you points on the ladder by 0.3 to get extra credit.
