for Final Exam (December 15, 2005)

Announcements:



The Final Exam is scheduled for:

Thursday, December 15, 2005 from 1:30pm - 3:30pm
in CHE 2110


Note that this is a Uniform Final. That is, the time and date of the final cannot be rescheduled. If you are enrolled in more than one mathematics course with a uniform final, University policy dictates that you take the uniform final for the highest numbered course and schedule a makeup for the lower numbered courses. In particular, if you are taking both MATH 240 and MATH 241, you take the uniform final for MATH 241 and schedule a makeup exam for MATH 240.


If you are registered concurrently for MATH 246:
There will be a scheduled Math 241 Alternate Final Exam Date. The final will be held on Friday, December 16, 2005 from 10:30-12:30 in CSS 2416. Note: this alternate final will be administered only to those people registered for MATH 246.

  • The grades are in! Here is the breakdown on grading:
    Total Points Recieved Grade Received Number of Recipients
    655-800 A 16
    580-654 B 20
    465-579 C 10
    435-464 D 4
    Below 435 F 7

    My two cents:

    Experience has shown that the key to success is working smart. Here are some ways that you can guarantee success in this course:

    Read the text as the material is covered (reading ahead is often best)
    Be prepared to ask and answer questions about the material in class.
    “The BEST way to learn Mathematics is to DO Mathematics.” Always attempt problems before seeking help.
    Start the homework well in advance. Waiting until the last minute is ALWAYS a bad idea.
    Expect to spend at least 10 hours a week on the homework/reading (that’s 2 hours per hour of classtime).
    Form a study group to discuss problems but DON'T form "Copy Sessions"
    Be an active learner. Practice Mathematical Skepticism. Don't be afraid to ask "why?" or "how?"
    Take advantage of all available tools: Attend class regularly, participate in class, visit office hours and always check for new announcements.



    Quizzes and Solutions:


    Quizzes will be given frequently throughout the semester and will be administered near the end of the discussion section. There will be approximately 10 quizzes throughout the semester.

    Each quiz will be worth 20 points and generally, there will be three questions. Each quiz covers any material, including material covered in Math 115, 140 and 141, taught before the quiz date. You will have approximately 15 minutes for each quiz. The solutions will be posted by noon (of the quiz day). There will be no makeup quizzes . At the end of the term, only the 5 highest quiz scores will be counted towards your quiz average.

    Quiz 1 - 09/06 sec 11.1, 11.2, 11.3 Cartesian Coordinates, Vectors in 2 and 3 space, The dot product
    Quiz 2 - 09/15 sec 11.2, 11.3, 11.4,11.5,11.6 Applications of the dot product, Equation of the line and plane
    Quiz 4 - 10/06 sec 12.2, 12.3, 12.4 Limits and Continuity of multivariable functions, partial derivatives and the chain rule
    Quiz 6 - 10/27 sec 14.1, 14.2 Double Integrals in Rectangular and Cylindrical Coordinates
    Quiz 7 - 11/01 sec 14.3, 14.4,14.5 Multiple Integrals and Surface Area
    Quiz 9 - 11/22 sec 15.1, 15.2 Vector Fields and Line Integrals
    Quiz 11 - 12/01 sec 15.1, 15.2,15.3, 15.4 Vector Fields, Line Integrals and Green's Theorem



    MATLAB and Solutions:


    There will be 5 MATLAB assignements throuhout the semester. Each MATLAB assignment will be worth 25 points and the lowest grade will be dropped.

    You are strongly encouraged to work in groups of three. Groups of two are acceptable and groups of four require permission. To obtain permission for such groups, email me before the assignment is due (almost invariably, permission will be granted).

    Before the first MATLAB assignment is due, there will be a MATLAB demonstration during the discussion section.

    Report Details


    Each Group submits one MATLAB report.

    Published mfiles (new for MATLAB7) are preferred.

    When the MATLAB reports are collected, each group member will also submit an Individual Effort Report.

    Late projects will be accepted with a 5 point deduction per class period (i.e, if the report is due on Tuesday, A late "25" report will earn 20 points if turned in by Thursday, 15 points by the following Tuesday, etc.).

    Approximately one week after each MATLAB assignment due date, I will post a model solution. After the model solution is posted, reports will no longer be accepted.

    MATLAB Materials

    Professor Rosenberg has compiled several MATLAB lessons, demonstrations and mfiles for his sections of Math 241. Definitely refer to this page for assistance. Note: Exam Dates and Homework Assignments apply only to Professor Rosenberg's sections

    Supplementaries:

    From time to time, I'll post supplementary Handouts. They are intended to help you study for the midterms and the final exam. Many are summaries of techniques used for the quizzes, while others are extra problem sets. Occasionally, I will post review material (from previous courses) and "tangentially speaking" handouts (which I discuss special topics). I strongly encourage you to view these as well. I assure you that I won't spend time preparing and posting anything that won't be beneficial to you.

    Challenge Problem:


    Throughout the semester, you will be given the opportunity to flex your brain muscles by working on these challenge problems. The challenge problems are closely related to the material being discussed in the course, though they are always much more theoretical and/or require a little more thought than the regular course material.

    Rules of the Challenge Problem

    There will be four challenge problems throughout the semester. While there is no official deadline to submit solutions, A challenge problem will close (that is, submissions will no longer be accepted) approximately one week after a complete and correct solution is submitted. As soon as the problem closes, I will post the correct solution. Since it is impossible to tell when a correct solution will be submitted, it is best to submit your solutions as soon as possible.

    This is an individual effort. However, you may consult other books or people (including classmates), as long as you acknowledge every source used. Since it is sometimes difficult to differentiate original work from duplicated work, if identical solutions are presented, neither solution will be accepted. If your solution is rejected for this reason, you have the option of resubmitting the solution (until the problem closes). Should you need to resubmit a solution, your maximum point value decreases by 2 points (i.e. the second resubmission recieves up to 3 points, the third up to 1 point).

    Each challenge problem is worth up to 5 bonus quiz points. In particular, the points earned through solving the challenge problems can collectively replace a low quiz grade.

    CP #1 Closed
    CP #2 Closed
    CP #3 Open
    CP #4 Open
