• Text: McCallum,Hughes-Hallett, et.al., Multivariable Calculus, Fifth Edition, with WileyPLUS.
• Online Homework: We will use online homework WileyPLUS.
  See information below.
• Calculators: A graphing calculator is required.
• Instructor: Barbara Kaskosz, Lippit Hall 202J, 874.4445, bkaskosz@math.uri.edu. Office hours: Tue 11-12,

WileyPLUS Registration and the first five WlieyPLUS assignments are posted.

We will be using WileyPLUS online homework system in this course. To sign up for the WileyPlus system, you will need a WileyPLUS registration code.

If you buy a copy of our textbook at the URI Bookstore, a registration code for WileyPLUS will be included with the book at no additional cost.

If you have a registration code, you will be able to sign up for the WileyPLUS system by clicking on WileyPLUS Registration link posted above.

Help at AEC

THE ACADEMIC ENHANCEMENT CENTER: The work in this course can be difficult.  You can seek help at the Academic Enhancement Center (AEC) in Roosevelt Hall. For a complete schedule go to www.uri.edu/aec, call (401) 874-2367, or stop by the fourth floor in Roosevelt Hall.

Exams and Evaluation

There will be two exams (separate for each section):

EXAM 1: Mar 4, during regular classtime, Lippitt 204;
EXAM 2: April 22, during regular classtime, Lippitt 204.

The FINAL EXAM (separate for each section) will take place during the time scheduled for your section by the Office of Enrollment Services: http://www.uri.edu/es/calexams/examScheduleFall2009.html in Lippitt 204. That is:

SECTION 2 (T,Th 9:30-11:45) FINAL: Thursday, May 6, 8 am - 11 am, Lippitt 204.

SECTION 4 (T,Th 12:30-1:45) FINAL: Tuesday, May 11, 11:30 am - 2:30 pm, Lippitt 204.

Your grade will be based upon a possible total of 650 points, as follows:

• Two common tests at 150 points each -- 300 points,
• Final exam -- 200 points,
• Quizzes and WileyPLUS Homework -- 150 points.

Mathlets

You may find the following applets useful.

• Contour Diagram Plotter and 3D Function Grapher Combined  Plot contour diagrams of functions of two variables. Draw the 3D graph of same function in and compare the two ways of visualizing functions of two variables.
• 3D Function Grapher  The user enters a formula for f(x,y) and the x and z ranges.
• Parametric Curves and Motion in 3D  The user enters parametric equations for an arbitrary curve in xyz-space. The curve can be traced while the velocity and the acceleration vectors are displayed as well as their approximate values.
• Parametric Surfaces in Rectangular Coordinates  The user enters parametric equations for rectangular coordinates, the applet draws a surface that can be rotated in real time.
• Parametric Surfaces in Cylindrical Coordinates  The user enters parametric equations for cylindrical coordinates.
• Spherical Coordinates Presented Interactively  Become familiar with spherical coordinates. Enjoy many practice problems.
• Parametric Surfaces in Spherical Coordinates  The user enters parametric equations for spherical coordinates.
• Regions Described by Double Integrals  Enter limits in double integrals in rectangular and polar coordinates to see the region described by those limits. Practice finding limits which describe a given region.

Maple Worksheets

Maple is a great tool for visualizing multivariable calculus concepts as most of the time their geometrical interpretation is in the 3D space. Below are links to a couple of Maple worksheets that will help you get started with Maple for multivariable calculus.

Each Maple worksheet is posted in two forms: as an interactive worksheet with the extension 'mw', say, graphs_m12.mw, and in the non-interactive 'html' form. The 'mw' worksheets have been created in Maple 12 so you may not be able to open them in earlier versions of Maple.

To download an interactive worksheet, right-click on it, go to 'Save Link As' and save it with the extension 'mw', say, 'graphs_m12.mw'. Or left-click on it and save what ever opens as say, 'graphs_m12.mw'. Once you save a 'mw' file, open it in Maple.

Illness Due to Flu

The H1N1 Flu Pandemic may impact classes this semester. If any of us develop flu-like symptoms, we are being advised to stay home until the fever has subsided for 24 hours. So, if you exhibit such symptoms, please do not come to class. Notify your instructor of your status via email, and we will work together to ensure that course instruction and work is completed for the semester.

The Centers for Disease Control and Prevention have posted simple methods to avoid transmission of illness. These include: covering your mouth and nose with a tissue when coughing or sneezing; frequently washing your hands to protect from germs; avoiding touching your eyes, nose and mouth; and staying home when you are sick. For more information, please view http://www.cdc.gov/flu/protect/habits.htm . URI information on the H1N1 will be posted on the URI website at www.uri.edu/news/h1n1.html with links to http://www.cdc.gov site.
