Prerequisite: A grade of C in Math 126, or the equivalent.

Corequisite: Chem 321 and 322 and EE 201. If you are planning to go on to Math 325, you should take Math 224 and Math 207 concurrently.

Postrequisites: This course is a prerequisite for EN 231 and 571, Math 307, 320, 325, 330, 337, 345, 445, and 480, and Phys 323.

Course Content/Objective: The Catalog says that this course covers

Differentiation and integration of trigonometric, logarithmic, and other transcendental functions. Infinite sequences and series, parametric representation of curves, and selected applications.
This amounts to a continuation of the methods and applications of one-variable calculus, including games with inverse functions, more techniques and applications of integration, sequences and series, and some parametric equations and polar coordinates.

Attendance, work load: Regular attendance in class is a key to success — don't skip class, don't be late. But more than merely attending, you are also expected to be engaged with the material in the class. In order for this to be possible, it is necessary to be current with required outside activities such as reading textbook sections and doing homework problems: you are expected to spend 2-3 hours per hour of class on this outside work. This is not an exaggeration (or a joke!), but if you put in the time and generally approach the class with some seriousness you will get quite a bit out of it (certainly including the grade you need).

If you absolutely have to miss a class, please inform me in advance (as late as a few minutes before class by phone or e-mail would be fine) and I will video the class and post the video on the 'net. You can then watch the class you missed in the comfort of you home and (hopefully) not fall behind. Classes I have videoed will have the icon Black and white camera icon next to that day's entry on the schedule/homework page to remind you of the available video.

Calculators: Students are required to have and to become (somewhat) familiar with the basic functioning of a graphing calculator such as the Texas Instruments TI-8x. Your calculators will be permitted (suggested) for (large parts of) all of our exams — while symbolic calculators (like the TI-89) will be forbidden.

The Mathematics Department does have a TI-84 Plus calculator rental program, with rental of a limited number of calculators available on a first come, first serve basis for a non-refundable fee of $20 per semester payable at the Bursar's window in the Administration Building. For more information, contact Prof. Tammy Watkins in the Math Learning Center (PM 132).

Homework: Mathematics at this level is a kind of practical (although purely mental) skill, not unlike a musical or sports skill — and, like for those other skills, one must practice to build the skill. In short, doing problems is the only way truly to master this material (in fact, the only way to pass). To this end, there will be daily, fairly extensive homework set. Similarly, we will spend a good part of our time in class discussing problems. In fact, I am happy to work with you during class time on the homework set due on the following day (or even due that very day).

Here are some specifics:

Big Ideas [BIs]: Along with every homework set, you must turn in a written explanation of the Big Idea of the last class. This should be at least a clear and complete sentence, although sometimes several (or a paragraph, or an equation with explanatory sentences) will be more appropriate. The goal here is to get some practice with good exposition of mathematical facts and with mathematics as a body of general results and ideas, not merely a collection of worked examples. Some specifics:

Quizzes: Most Fridays, during weeks in which there is no hour exam, there will be a short (10-15 minute) quiz at the end of class. These will be closed book, but calculators will (usually) be allowed. Your lowest quiz score will be dropped.

Exams: We will have three in-class hour exams, on dates and covering material to be announced. Our (comprehensive!) final exam is scheduled for Wednesday and Thursday, December 10th and 11th, from 1-3:20am in our usual classroom.

Revision of work on HWs, BIs, quizzes, and tests: A great learning opportunity is often missed by students who get back a piece of work graded by their instructor and simply shrug their shoulders and move on — often depositing their graded work in a trash can without even looking at it! In fact, painful though it may be, looking over the mistakes on those returned papers is often the best way to figure out exactly where you tend to make mistakes. If you correct that work, taking the time to make sure you really understand completely what was missing or incorrect, you will often truly master the technique in question, and never again make any similar mistake.

In order to encourage students to go through this learning experience, I will allow students to hand in revised solutions to all homeworks, BIs, quizzes, and midterms. There will be an expectation of slightly higher quality of exposition (more clear and complete explanations, all details shown, all theorems or results that you use carefully cited, etc.), but you will be able to earn a percentage of the points you originally lost, so long as you hand in the revised work at the very next class meeting. The percentage you can earn back is given in the "revision %" column of the table.

Grades: On quiz or exam days, attendance is required — if you miss a quiz or exam, you will get a zero as score; you will be able to replace that zero only if you are regularly attending class and have informed me, in advance, of your valid reason for missing that day.

In each grading category, the lowest n scores of that type will be dropped, where n is the value in the "# dropped" column. The total remaining points will be multiplied by a normalizing factor so as to make the maximum possible be 100. Then the different categories will be combined, each weighted by the "course %" from the following table, to compute your total course points out of 100. Your letter grade will then be computed in a manner not more strict than the traditional "90-100% is an A, 80-90% a B, etc." method. [Note that the math department does not give "+"s or "-"s.]

  pts each # of such # dropped revision % course %
Quizzes: 10 ≈10 1 33.3% 14%
Homework: 3/prob ≈55 sets
≈175 probs
17 probs 75% 14%
Big Ideas: 2 ≈55 (≈1 per
HW set)
3 50% 4%
Midterms: >100 3 0 33.3% 42%
Final Exam: >200 1 0 0% 26%

Contact outside class: Over the years I have been teaching, I have noticed that the students who come to see me outside class are very often the ones who do well in my classes. Now correlation is not causation, but why not put yourself in the right statistical group and drop in sometime? I am always in my office, PM 248, during official office hours. If you want to talk to me privately and/or cannot make those times, please mention it to me in class or by e-mail, and we can find another time. Please feel free to contact me for help also by e-mail at jonathan.poritz@gmail.com, to which I will try to respond quite quickly (usually within the day, often much more quickly); be aware, however, that it is hard to do complex mathematics by e-mail, so if the issue you raise in an e-mail is too hard for me to answer in that form, it may well be better if we meet before the next class, or even talk on the telephone (in which case, include in your e-mail a number where I can reach you).

A request about e-mail: E-mail is a great way to keep in touch with me, but since I tell all my students that, I get a lot of e-mail. So to help me stay organized, please put your full name and the course name or number in the subject line of all messages to me. Also, if you are writing me for help on a particular problem, please do not assume I have my book, it is often not available to me when I am answering e-mail; therefore, you should give me enough information about the problem so that I can actually help you solve it (i.e., "How do you do problem number n on page p" is often not a question I will be able to answer).

Academic integrity: Mathematics is more effectively and easily learned — and more fun — when you work in groups. However, all work you turn in must be your own, and any form of cheating is grounds for an immediate F in the course for all involved parties. Please do not use a cell phone during class. You may not use a cell phone or share a calculator with another student during a test.

Nota bene: Most rules on due dates, admissibility of make-up work, etc., will be interpreted with great flexibility for students who are otherwise in good standing (i.e., regular classroom attendance, homework (nearly) all turned in on time, no missing quizzes and tests, etc.) when they experience temporary emergency situations. Please speak to me — the earlier the better — in person should this be necessary for you.

Students with disabilities: The University abides by the Americans with Disabilities Act and Section 504 of the Rehabilitation Act of 1973, which stipulate that no student shall be denied the benefits of education "solely by reason of a handicap." If you have a documented disability that may impact your work in this class for which you may require accommodations, please see the Disability Resource Coordinator as soon as possible to arrange accommodations. In order to receive accommodations, you must be registered with and provide documentation of your disability to: the Disability Resource Office, which is located in the Library and Academic Resources Center, Suite 169.
