Summer I 2025
Western Michigan University
Instructor:
Office:
My office is 5524 Everett Tower. I will be in my office for students during my office hours as listed in my schedule. No appointment is necessary during those times. I will usually have my Webex room open during those times, https://wmich.webex.com/meet/jay.treiman. You can also make an appointment at another time.
Textbook:
Draft text by Jay Treiman. This will be available through elearning.
Maple 2024: The code to purchase Maple at a discount is in the content section of elearning.
Catalog description:
Vectors and geometry in two and three dimensions, matrix algebra, determinants, vector differentiation, functions of several variables, partial differentiation, linear transformations, multiple integration, and change of variables. The computer algebra system Maple will be used to explore some of these topics.
Note: A graphing calculator is required.
Prerequisites and Corequisites: Prerequisite: MATH 1230. A grade of āCā or better is required to satisfy any course prerequisite.
Course objectives:
General:
This class is an on-line synchronous class from 6:00 to 7:40 PM on MTuWTh. Even though roll will not be taken, all students attend class every day.
The class sessions will be recorded and the recordings should be linked to the content section in elearning. The written and Maple work done from class sessions will also be posted to the content section of e-learning. The files containing the writing will be in the format for Xournal++. There may be problems to be done during these sessions.
The prerequisite for this class is Calculus II, Math 1230 at WMU. It will also be helpful for this section if you have some science background. We will try to include applications from science and engineering in this class.
You are responsible for all material in the text and all material presented in the class sessions. This includes any material not in the text presented in the class sessions and all material in the text that was not presented in the class sessions. A list of topics is available. This course will mostly follow the order of the material in the draft text.
It is expected that you will spend at least 3 to 4 hours working on Math 2720 outside the class sessions for every credit hour for class. Most students who do not spent enough time on this class do not pass.
A list of expectations for students and the instructor is available.
You are expected to follow all university conduct policies. This includes giving credit on any assignment you turn in for any help you receive and referencing any resources you use that are not from the text or the lectures.
There are some other university policies. you should be aware of.
The last day to withdraw is June 2, 2025. A tentative schedule is available.
Calculators:
A TI CAS graphing calculator is highly recommended. You will use many of the extra features of these calculators, including their symbolic computation abilities. It is expected that you have a graphing calculator for this class, e.g. a TI-84. As an instructor I will be using Maple for illustrations and computations during class. The TI calculators will be allowed during quizzes and exams if they do not have wifi capabilities or programs that produce answers to calculus questions.
Tutoring:
There are many places on campus where tutoring is available. Do not hesitate to get help if you are lost. Among the places where tutoring for Math 2720 is available are the mathematics tutoring lab and the Bronco Study Zone.
When working with a tutor, please remember that you are restricted to the notation for this class. It is also necessary to learn the techniques in this class since some exam and/or quiz problems will restrict the techniques you can use to solve the problems. Any work you turn in must include the name and location of a tutor who helped you. This will not reduce your grade on a problem.
Homework:
A portion of your grade will come from homework and quizzes. A list of problems to work will be on this web site. Assignments to be turned in will be posted in the dropbox section of elearning. Although some of this homework will be collected, you are responsible for all of the problems on the list. If you have any questions about homework problems, please ask them in class, in office hours, via e-mail, or by making an appointment for a personal session.
All written homework will be submitted as a PDF file through a dropbox in e-learning. Submit all written assignments as a single PDF file containing the solutions to all of the assigned problems. The problems must be legible and in order of section and the numerical order, e.g. section 2.1 problem 1, section 2.1 problem 5, section 2.2 problem 2,... All pages in your PDF must be the same size. If a signed statement is required for the assignment, it is to be the first page of your submission with a written, not typed, signature. Do not submit a zip file. Your name must be in the name of the file. Make certain that you have clicked the submit button for the dropbox in e-learning.
If I cannot read the assignment or there are other problems with it, I reserve the right to not grade the assignment. For those using a cell phone to scan your assignments, I recommend using either Adobe Scan or Microsoft Lens.
If you get help from a tutor or someone else on a written assignment, that must be noted on your submission. You will not lose points for getting help, but I want to know if a tutor is using methods or notation that are not appropriate.
On-Line Homework:
There will be on-line homework. Access to the on-line homework will be through elearning. For many of the problem Maple syntax is required/usable for the on-line homework. Unless otherwise requested, give exact answers for all problems in Mobius. Last minute questions about formatting or what is going wrong may be left unanswered. Professors also need to sleep.
Please do the on-line homework. Most people who do not pass this class do not do the on-line homework. Please do not spend too much time on the on-line homework. The problems may require a lot of computation, but they are only the basics of what you should learn. Using Maple or a calculator for complex computations is allowed for the Mobius homework. On exams you are required to show your work, so not working many of the problems by hand could cause you difficulties.
After the assignments are due you should have access to your old assignments along with answers using the Mobius gradebook link in the content section of elearning. If I forget to change the access to the answers for an assignment, please remind me.
Maple assignments:
There will be assignments using Maple, a computer algebra system. These assignments will be in drop boxes on WMU's e-learning system. All assignments must be turned in as a single Maple worksheet through e-learning. Do not submit a zip file. More details will be available later.
Exam:
One midterm exam will be given. The date is on the tentative schedule. Information about the format of the exam will come later.
Final Exam:
A final exam will be given. The final exam will be given on June 24, 2025 during the regular class time. The final exam will be comprehensive.
Grading policy:
All exams will follow the following outline: 50% of the questions are things you must be able to do, 25-30% of the problems are things you should be able to do, and 20-25% of the questions are more difficult. It is not uncommon for averages to be around 60% or lower.
To pass this class with a "C" you must demonstrate that you can do all of the required material. A starting scale is: A 85%+; BA 78+; B 72+; CB 66+; C 58+; DC 52+; and D 46+. This scale will probably change as the term progresses. Often the bottom C grade is around 50%. The lowest C grade will not go below 50%.
The distribution of points for calculating grades is as follows. The final exam is worth 35%, the midterm exam is worth 25%, and the quizzes, homework, Maple, and other assignments are worth 30% of your grade. The on-line homework is worth 10% of your grade.
