WileyPLUS Online Homework System

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 buy a copy of our textbook somewhere else and it does not include WileyPLUS code, you will need to purchase a WileyPLUS code separately.

The following flyer explains what comes with the registration code. In particular, a code gives you access to the electronic version of the textbook. The flyer also explains how to register for your section of MTH 243 once you have a code:

When you are ready to register for WileyPLUS, the following tutorial explains how to do it:

As the flyer and the tutorial direct you, you go to the WileyPLUS main site: WileyPLUS, click on Get Started, enter University of Rhode Island as your school. You will see a list of courses, MULTIVARIABLE CALC, as one of them. Open the menu by clicking the plus sign next to the courses's title. You will see a list of sections, among them Section 2 (TR 9:30) and Section 3 (TR 12:30). My name 'Kaskosz' is also listed there. Choose your section and proceed to register.

Exams and Evaluation

There will be two exams during the semester: Exam 1: Thu, Feb 28; Exam 2: Thu, Apr 11, both in class. The final exam is scheduled by the Office of Enrollment Services based on the time your section meets: Final Exam Schedule.

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

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

Graphing calculators will be allowed on all quizzes and exams but not other electronic devices. Class attendance will not be taken but you should consider your presence and participation in class to be very important to your learning process and ultimately to your success in this course.

Available Help

MTH 243 is a difficult course and you may need help often. There will be much help available during the semester.

• Your instructor's office hours: TR 11-12, T 2-3, Lippitt 202J.
   
• You will find help at Lippitt at Math and AEC Walk-In Tutoring Center: Spring 2013 Tutoring Schedule.

Technology

You may find the following applets useful and illuminating. (The applets require Flash Player.)

• 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.

Course Description

MTH 243 is a demanding course for students in the STEM disciplines. In order to succeed in this course, you will have to work systematically and hard. In this course we will cover the central topics in the calculus of functions of two and three variables as well as elements of vector analysis. This material is of great importance in engineering, physics, chemistry and other STEM disciplines. Take a look at the syllabus for the list of specific topics: Calendar and Syllabus.

Course Goals and Learning Outcomes

During the course you should be able to build proficiency in working with functions of more than one variable as well as vectors and operations on vectors. You will learn about partial and directional derivatives of multivariable functions, gradients, double and triple integrals. You will learn about vector fields and line integrals.

Ilness Due to Flu

The nation is experiencing widespread influenza-like illness. 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 me at bkaskosz(AT)math.uri.edu of your status, and we will communicate via email. 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 tissue when coughing or sneezing; frequent washing or sanitizing your hands; avoiding touching your eyes, nose, and mouth; and staying home when you are sick. For more information please view www.cdc.gov/flu. URI Health Services web page will carry advice and local updates.
