I want all of you to succeed in this class; below you will find
some tips for how you can help make this happen.

The course syllabus (it covers some of the same things as this web-page, but it covers other things too; you need to read both).

The textbook for the course (Applied Discrete Structures 3rd edition by Alan Doerr and Kenneth Levasseur). For each mistake you find in the book that I don't already know about, you'll earn a dollar!

Extra readings assigned throughout the semester: cong.pdf, exponomial.pdf, factorial.pdf, induction.pdf, multiply.pdf, and unique.pdf.

Lecture-by-lecture reading-and-thinking assignments (subject to continual update).

The Piazza page for the current semester of 92.2190.

Lecture capture. Log in and select "MATH.2190-204 Discrete Structures I (Formerly 92.321)".

Homework problems and solutions.

The UML tutoring page.

The Essence of Linear Algebra video series is a good intro to linear algebra (which is part of the syllabus of the course).

Francis Su's guidelines for good mathematical writing.

Dave Richeson's essays The Nuts and Bolts of Writing Mathematics and Editing a Very Poorly Written Proof.

My views about being wrong. See especially the section under the heading "MISTAKES INSIDE AND OUTSIDE THE CLASSROOM".

A practice first exam. (Note: The practice exam is not intended as an indication of the level of difficulty of the actual exam; in the past, students have felt that the actual exam was harder than the practice exam.)

A practice second exam. (Note: The practice exam is not intended as an indication of the level of difficulty of the actual exam; in the past, students have felt that the actual exam was harder than the practice exam.)

Drop-in Hours: Tuesdays and Thursdays, 12:00-12:25 and 3:20-3:45. Meetings at times other than my drop-in hours can be arranged by appointment; see me after class, call me on the phone, or send me an email message.

Suggestions about how the course is being run are welcome at any time. If something isn't working for you, please don't wait until the end of the semester to tell me!

Meeting place: Olsen 104.

Expectations: You're expected to attend classes, do the reading in advance, ask questions, and make serious attempts to answer questions raised by me or by other students during class. If you miss a class, it's your responsibility to make sure you obtain all information (course material, assignments, changes in exam dates, etc.) presented that day.

**Exam dates**: October 23 and December 13.

It's important that everyone take the same exams under the same
conditions for maximum fairness and reliability of testing. I therefore
don't give makeup exams unless you have a valid reason for missing
the scheduled exam (for example, illness or a religious holiday), and I
don't allow extra time on exams unless you have a note from Disability
Services (see below).
**If you have to miss a scheduled exam, please let me know
ahead of time if at all possible**; I'm much more likely to be
sympathetic if you call me the morning of the exam and say “I have the
flu and can’t take the exam” than if you come in two days after the
exam and say “I missed the exam. When can I take a makeup?”

You may not use a cell phone in any way during an exam.

Use of calculators is prohibited during exams.

You can always reschedule an exam
that falls on a day that is a religious holiday for you, but you must
make these arrangements ahead of time.

Tips on Taking Exams

Typically there'll be one homework assignment per week, due one week after it is assigned.

In order for you to understand the material in this course, it's extremely important that you do the assigned homework problems. Working with your classmates can be a great help, and I strongly encourage it, subject to certain provisos (see below). I also urge you to ask questions about any problems that give you trouble.

Homework will usually be due each week on Thursday. Your grade will be based on clarity as well as correctness, so neatness, grammar, and punctuation should not be neglected. Harder problems will in general be worth more points. However, it will not be possible to grade all problems. You are encouraged to give me feedback about the homework; for instance, if one of the problems was a huge time-sink, I want to know about it!

**Late homeworks will not be accepted**.

Each student will be allowed to skip one assignment without penalty, because the lowest homework score does not count toward the final grade. Don't use up your “free skip” too early in the semester!

While you can discuss the exercises with classmates, the work you hand in
should be your own write-up and not copied from someone else. When leaving a
joint homework-solving session, don't carry away anything that doesn't fit
in your own brain. Also, **you must acknowledge who you worked with.**
(If you didn't work with anyone, you must write “I worked alone on this
assignment”.)

Points may be deducted from students who repeatedly fail to state whom they worked with.

Academic honesty in homeworks is expected. (E.g., if you use web-resources or tutors or collaborators of any kind, the role of their contribution must be acknowledged; you won't receive a lower grade for using such resources, but if the grader and I feel you're relying on them too heavily, we may require you to change your way of doing homework.) My expectations for appropriate ways of doing the homework will be discussed in class; in case you are in any doubt about what is expected, it is your responsibility to contact me for clarification.

It is not required that you submit your solutions in LaTeX, but if you are planning to be a mathematician, scientist, or engineer, it's never too early to learn! LaTeX is free software that lets you typeset formulas about as fast as you can write them (with some practice). Composing your homework in LaTeX will help you pay attention to your communication of mathematics, and make it much easier to edit your work as you go along. There will be an initial hump of getting started, but after a couple of problem sets, using LaTeX will become quite natural. You'll probably still want to draw your diagrams and figures free-hand, but knowing how to write equations in LaTeX is a life-skill that will serve you well in later courses in which homeworks involve fewer pictures and more formulas.

Also, you may want to use Mathematica as an aid to your learning. UML students will be able to download Mathematica as part of the campus license. You shouldn't use Mathematica as a substitute for being able to do the work yourself the old-fashioned way, but it's a great way to check your work. Also, Mathematica features many demonstrations (see http://demonstrations.wolfram.com/) that can bring course material to life in a vivid way.
