Introduction: Welcome to MAT 111, a course in college algebra. We will be studying important algebraic concepts and applications that are particularly useful in UNCW classes that have MAT 111 as a prerequisite. Topics include equations, inequalities, functions and graphs (including linear, quadratic, polynomial and rational functions, exponential and logarithmic functions), complex numbers, and systems of linear equations. Technology –the graphing calculator, will be used as a powerful tool for conceptualizing and aiding in the solution of diverse and interesting problems.

Text: Algebra and Trigonometry: A Graphing Approach, by Larson, Hostetler, and Edwards, Second Edition, Houghton Mifflin Company (referred to as LHE).

1. Graphing Technology Guide, by Benjamin N. Levy and Laurel Technical Services (referred to as GTG).
2. Study and Solutions Guide, by Edwards and Zook.
3. A graphing calculator. The TI-82 is used for all in-class calculator discussion. Students who use another calculator are responsible for making necessary adjustments. The Graphing Technology Guide provides assistance for a wide variety of Texas Instruments, Casio, Sharp, and Hewlett-Packard graphing calculators.

Course Objectives: Our goal is to obtain a useful mastery of algebraic concepts and methods basic to further work in mathematics and areas of application such as business, nursing and the sciences. To enhance your ability to formulate and solve applied problems, to interpret graphs and functions and to use them effectively so you may enjoy the triumph of discovery that comes from solving a problem by your own means. To this end we will learn some new techniques, definitions, and algorithms which we apply to interpreting phenomena using a suitable mathematical model of your choosing to then analyze and draw valid conclusions. My goal is to help you learn how to think about functions and mathematical models so you can do well in this course and in your subsequent studies.

1. Attendance is expected unless extreme circumstances warrant otherwise. There are no make-up tests. See me (or e-mail) in advance if possible if you cannot make a test, or as soon as possible after missing a test if your absence may qualify as excusable.
2. Calculators may not be shared during tests.
3. Academic dishonesty is not tolerated. According to the UNCW Academic Honor Code (See Section V of you Student Handbook), anyone who knows of a violation of the Code, including giving or receiving information, is expected to report the violation to the course instructor. Please note that in this course, working together on homework is not a violation of the Honor Code. You are encouraged to discuss and compare work –but not to copy someone else’s work.

Gateway Quizzes: There will be two "gateway" quizzes on which you must score at least 70%. These quizzes are given outside class and may be repeated (in different versions) until you achieve 70% or better. Only your first quiz grade is recorded. Gateway Quiz #1 covers exponents and elementary algebra, with questions similar to those on the MAT 111 Review Sheet. Gateway Quiz 2 involves translating verbal descriptions of problems into appropriate expressions and equations. There is a penalty for failing to achieve 70% on gateway quizzes: 10% of your total will be deducted from all tests until you get 70% or better on quiz 1, and from all test except the first until you get 70% or better on quiz 2.

Other Graded Work: There will be 3 one-hour tests during the semester, each counting 25%. There will be a short daily quiz in class most days. The lowest 2 quiz grades will be dropped (this includes up to 2 zero grades for missed quizzes); the remaining quiz grades will be averaged and the result counted as a one-hour test (25% of your grade in the course). The final examination (a comprehensive exam, common to all sections of MAT 111) will replace your lowest test grade if this improves your average.

When the distribution of course grades suggests that a borderline grade might be raised to the next higher level, I consider such factors as attendance and improvement.

Important Date: Last date to Withdraw with a "W" –Wednesday, September 30, 1998.

Students with Disabilities: If you have a disability and need reasonable accommodation in this course, you should inform the instructor of this fact in writing within the first week of class or as soon as possible. If you have not already done so, you must register with the Office of Disability Services in Westside Hall (extension 3746) and obtain a copy of your Accommodation Letter. You should then meet with your instructor to make mutually agreeable arrangements based on the recommendations of the Accommodation Letter.

1. Use your Study Guide. It has a summary for each section of the text and answers for the odd-numbered problems.
2. Do some mathematics almost every day. You should plan on at least 6 hours of study time outside class per week. Read over your course notes and fill in gaps soon after class so your notes will be useful in later study.
3. Read the text and study guide with pencil and paper beside you, and use them. Understanding mathematics can’t be done just by watching a lecture or skimming the book.
4. It’s not enough to just do the homework. Ask yourself whether you could do other problems. Test yourself by recalling definitions and by doing additional problems.
5. In class, if you have a question, ask. It is likely that others have the same question. As you study make notes of concepts you don’t understand so you can ask in class or see me. For short questions, e-mail is a good choice.
6. If you need help, see me or visit the Math Lab, BR 101. Don’t let yourself fall behind.
7. Look back: how did I solve this problem, what can be learned from the mistake, or what other strategy could also have been effective in solving this problem?
