Please feel free to come by my office any time during scheduled
You are welcome to
come at other times, but in that case you might want to make
an appointment, just to make sure that I will be there then. You can
make an appointment simply by talking to me before or after class, by
calling me at
or at home, or by sending
You may also ask any questions directly via phone or e-mail. If I'm
not in when you call, please leave a message on the voice-mail or
answering machine with your name, number, and a good time for me to
call you back. I will try to respond to your phone or e-mail message
as soon as possible.
Calculus II (Math 1312). This is entirely a mathematical maturity requirement,
as we will use no calculus in this course.
Upon successful completion of the course, you will be able to
construct straightforward proofs in a variety of settings. You will
be able to make use of existing theorems, and employ basic
mathematical techniques of proof (induction, proof by contradiction,
contrapositives, etc.) and the building blocks of mathematical language (sets, functions, and relations). Your proofs will be in clear and complete
English sentences, accompanied by clarifying diagrams where necessary.
You will be prepared for further study of other specific topics in
This is very different from calculus and differential
equations, where you mostly performed computations to solve problems.
Although there is still problem-solving in this course, we will
emphasize proving your answers are correct, and not just finding answers. This is what almost all your future advanced math
courses will be like.
Chapter Zero, 2nd. ed., Carol Schumacher, Chs.
This book differs from other
texts for proof-based courses, in that the proofs of the theorems are
not included. The point of this is for you, the student, to fill in
these details, in order to be more actively involved with the
material. To make this task more manageable, intermediate results to help guide you are included. Read pages xiii-xiv of
the preface ("A Note to the Student: What This Book Expects from
You") carefully for more details.
The course is built around student presentations of proofs of results, and solutions to problems, from the textbook, while I serve as moderator. (I will also occasionally give short presentations to put topics into a wider context.)
I will announce the approximate schedule I expect us to follow about one week in advance, and maintain that information on the course
Each result or problem will have a due date for you to turn in your solution, before we discuss it in class. I will grade these mostly for effort. Keep a copy of your work; I will not return it until after we discuss it in class!
I will pick students (sometimes asking for volunteers on harder proofs) to present their work in class. I will sometimes use your written solutions (which you submitted in advance) to pick who will present a problem.
Presentations will be evaluated on: the quality and correctness of the content; the clarity of the presentation; the difficulty of the problem; and the frequency of your contributions. Making substantial progress, or asking a good question, about a harder problem without solving it may be worth as much as solving an easier problem.
When you are in the audience, you are still expected to be actively
engaged in the presentation. This means checking to see if every step
of the presentation is clear and convincing to you, and speaking up
when it is not. Note that by speaking up in these situations, you will probably help the presenters' grades, by giving them a chance to improve their presentation! When there are gaps in the reasoning, the class will
work together to fill the gaps.
Your presentations, audience participation, and advance written solutions will contribute to this portion of your grade, though presentations will count approximately twice as much as the other two components combined. Your grade will be based on your overall contribution to keeping the course moving (which includes forward progress, making sure presentations are complete and correct, helping other students' understanding) and on your ongoing understanding of the material. I will use the following rubric:
Written homework will be assigned approximately biweekly, announced in class,
and posted on the course website. These solutions should be written clearly and completely.
Assignments will be due at the beginning of class.
No late homeworks! (Incomplete homeworks will be accepted, though.)
If an emergency prevents you from delivering your homework on time (or
having someone else deliver it for you), please let me know as soon as
- A Clear, correct presentations to most problems; helpful audience participation including appropriate feedback and good questions; almost all problems written up in advance.
- B Correct presentations to routine problems; active audience participation including questions and discussions; almost all routine problems, and some harder problems, written up in advance.
- C Correct presentations to easier problems, and reasonable attempts at routine problems; responding in the audience when called on, posing questions when you are confused, and participating in discussions; most routine problems written up in advance.
- D Less than satisfactory work, but an apparent honest effort to understand material. At least some presentations with reasonable attempts; participating in the audience with questions or comments; some problems written up in advance.
You are encouraged to work together on your homework, but you must
write up your solutions by yourself.
Exams (15% each)
There will be two in-class, closed-book exams on the following days:
- Fri., 27 Feb.
- Wed., 8 Apr.
Each exam will cover material from the beginning of the semester, though the second
exam will focus more on material since the first exam. Makeup tests can be given only
in extraordinary and unavoidable circumstances, and with advance notice.
The final exam will be comprehensive over all material we discuss in class. The
final will be on
Wed., 13 May, 1:00-3:45 p.m.
You may not consult books, the Internet, other people outside of class, or
other sources to solve the problems or write your solutions. I do strongly encourage
you to work with your classmates on the problems in advance. I also encourage you
to talk to me frequently, more than in other courses. Feel free to ask questions about
the material, show me your work before presenting it in class, and even just talk about
Academic dishonesty: It is UTEP's policy, and mine, for all suspected cases or acts of alleged scholastic dishonesty to be referred to the Dean of Students for investigation and
appropriate disposition. See Section 1.3.1 of the Handbook for Operating Procedures.
Due to the course structure, attendance is mandatory. For every three unexcused absences, you will receive a zero for an
in-class presentation. I will usually excuse an absence if you tell me about it
in advance, or, in cases of emergencies, as soon as possible afterwards.
Drop date: The deadline for student-initiated drops with a W is Friday, April 3. After
this date, you can only drop with the Dean's approval, which is granted only under
I hope everyone will complete the course successfully, but if you are having doubts
about your progress, I will be happy to discuss your standing in the course to help you
decide whether or not to drop. You are only allowed three enrollments in this course,
and students enrolled after Fall 2007 are only allowed six withdrawals in their entire
academic career, so please exercise the drop option judiciously.
Courtesy: We all have to show courtesy to each other, and the class as a whole, during class
time. Please arrive to class on time (or let me know when you have to be late, and
why); do not engage in side conversations when one person (me, or another student)
is talking to the whole class; turn off your cell phone (or at least set it to not ring out
loud), and do not engage in phone, email, or text conversations during class.
Disabilities: If you have, or suspect you have, a disability and need an accommodation, you
should contact the Disabled Student Services Office (DSSO) at 747-5148, firstname.lastname@example.org,
or Union East room 106. You are responsible for presenting to me any DSS accommodation letters and instructions.
Exceptional circumstances: If you anticipate the possibility of missing large portions of class
time, due to exceptional circumstances such as military service and/or training, or
childbirth, please let me know as soon as possible.
