Text: PRECALCULUS, Enhanced with Graphing Utilities, 4thEdition, by Sullivan, Sullivan
Course Description: This course is intended to prepare students for a science/engineering level course in calculus such as MA 181-182. This preparation includes necessary algebraic skills, comprehension of the general properties of functions, and specific properties of algebraic, trigonometric, logarithmic, and exponential functions. For computation of tuition, this course is equivalent to five semester hours and meets five hours each week; however, MA 180 is a four credit hour course.
Prerequisite: A grade of C or better in MA103 and MA105, appropriate score on mathematics placement test, or permission from the Mathematics Department is required.
Calculator: You will be allowed to use calculators, particularly with decimals, percents, and problem solving. This will enable you to concentrate on the process and not get bogged down in the calculations. I would suggest that you purchase a graphing calculator. You will be able to use the graphing calculators in your upcoming Mathematics courses. In general, calculators TI-83 (84) or TI-83 (84) Plus are preferred; however, TI 85 or TI 86 are also acceptable. TI calculatorsmay be borrowed from the math / science center on a daily basis. No one will be allowed to share a calculator during quizzes and exams.
Attendance: You are expected to attend every class, and have your textbook, paper & pencil and calculator with you. Observe that attendance will be considered in your performance in the class. If you miss a class you are responsible for getting the notes and assignments in on time. I expect you to arrive to class on time.
Please be aware that you may be dropped if you accumulate absences whose sum is equivalent to more that one week worth of classes. As a result a student may be dropped before or after the college official deadline date for “withdrawals with a W”.
Homework Binder: There are some bad work habits which may hinder one’s performance in a course such as this one. As an example, sloppy handwriting often causes careless mistakes that lead to unnecessary confusion and lack of confidence in one’s work. In order to ensure that your work for this course is organized, you will be required to have a 3-ring binder (or a folder of your choice) which contains separate sections for:
- Homework assignments
- Quizzes, tests and handouts ( such as syllabus )
- Class notes (unless you prefer to keep these in a separate notebook).
The homework assignments should be written neatly and should include only the relevant calculations, not messy scratch work. You should also include the statement of each problem. (For word problems, you can briefly summarize the statement using symbols, if necessary) Keep the various components of the binder file in separate sections (Do not mix your quizzes in with your homework) I will periodically look at your binder and may grade selected problems. (I especially will be interested in seeing your binder when you are not performing well on quizzes and tests.)
Grading Policy: Your final grade will be based on the following:
Quizzes160(8 Quizzes * 20 Pts Each)
Exam I150
Exam II150
Exam III150
Exam IV150
Final Exam240

Grading Scale
900 – 1000 = A
800 – 899 = B
700 - 799 = C
600 – 699 = D
599 and below = F
There will be no make-ups on homework assignments to be turned in, or quizzes.
No make-up exam will be allowed without a well-documented medical excuse.
Dropping:The last day to drop this class (Without a Grade) is September 25th.
Moreover, the last day to drop this class with a grade of W recorded is November 20th.
Supplementary Materials: The textbook comes with the following supplementary materials that are available in the Math/Science Center. Videotapes are available which are keyed to each section of the text. In addition, MathPro Explorer Tutorial Software is available which not only provides students with problems and interactive guided solutions keyed to each section of the text, but also contains embedded videos of the author working out problems in each section. Arrangements can be made with the math/science center to orient you to this new software.
Final Exam:Tuesday,December 18th2:45 to 4:45 PM Failure to take the final will result in an F for the course.
Math/Science Tutoring Lab:There is a tutoring lab in room 02 ofMacklinTower.
This service is FREEto students.
Please DO NOT WAIT TO THELAST MINUTE!
Go to the lab on a regular basis – get to know the facilities and the tutors. The lab phone number is (240) 567-5201.
Academic Honesty:Common examples of academic dishonesty and misconduct can be found below and in the Student Code of Conduct, Section IV. If you are in
doubt about what constitutes academic dishonesty, consult your professor or the Student Code of Conduct.
Examples of academic dishonesty include, but are not limited to using “cheat notes” during an exam, copying answers from another student, allowing another person to copy your
work, either inside or outside of class; using work form previous semesters; and copying from a book, magazine, Internet site, or brochure when writing a paper without giving credit
to the source.
Faculty members may impose grade sanctions for violations of academic ethics, normally ranging from a minimum of F on the assignment in which the dishonesty occurred to a
maximum of an F in the course. Faculty members may choose to impose different sanctions. Faculty members also have the prerogative of referring a case to the campus Dean of Student Development with a specific request that the dean consider imposing sanctions.
