1 MAT COLLEGE ALGEBRA Room H 114 (Monday/Wednesday 10:00 11:15) Fall 2012 Kamal P. Hennayake PhD Professor of Mathematics Office: H-120 Phone: Ext Chesapeake College Wye Mills, Maryland khennayake@chesapeake.edu

2 INSTRUCTOR: Dr. Kamal P. Hennayake - Office H 120; Phone Ext (Voice Mail) khennayake@chesapeake.edu COURSE DESCRIPTION: A college level algebra course for students not majoring in mathematics, engineering, or the physical sciences. Topics included are the real number system, algebraic, exponential, logarithmic, and polynomial functions; rational polynomials, systems of equations, and appropriate applications. PREREQUISITE: Appropriate score on placement test, or MAT 032. REQUIRED COURSE MATERIALS: TEXTBOOK: College Algebra, Fifth Edition, by Robert Blitzer Prentice-Hall, Inc. ISBN Make sure to get MyMathLab (MML) student access kit with the textbook. CALCULATOR: Texas Instruments TI-83+ is recommended. INTRODUCTION: College Algebra is a prerequisite for many courses that involve mathematical applications. It provides a good background for many college level courses in a broad range of academic disciplines. The topics covered are included in the "Course Description" and computer software/graphing calculators may also be used to further illustrate specific concepts. As you begin your study of College Algebra, you may feel overwhelmed by the number of theorems, definitions, procedures, and equations that confront you. You may even wonder whether or not you can learn all of this material in the time allotted. These concerns are normal. Keep in mind that many elements of College Algebra are all around us as we go through our daily routines. Many of the concepts you will learn to express mathematically, you already know intuitively. For many of you, this may be your last math course, while for others, just the first in a series of many. Now that you have decided to take this course, remember that a positive attitude will make all the difference in the world. Your belief that you can succeed is just as important as your commitment to this course. Make sure that you are ready for this course by having the time and positive attitude that it takes to succeed. Specific suggestions for being successful in this course: Attend all classes. Students whose attendance is sporadic often do not do well because of the nature of the course, especially in the accelerated format. Most students need guidance in understanding the procedures involved in developing a new mathematical process. If you find yourself unable to keep up with the class, make an appointment immediately to see the instructor outside of class time. It is the student's responsibility to make up any work missed due to an absence for any reason. Read the book. In addition to arriving for class on time and being prepared, you will find it useful to read the section before it is covered in class. This will give you a clear idea of the new material that will be discussed. Work problems every day and check your answers. In addition to the lectures, the average student should plan to spend at least nine hours outside of class each week (3 hours for every hour spent in class). Students whose background in mathematics is below average, or who normally work at a slower than average pace, should schedule more time in order to keep up with the course material. The homework assigned represents the minimum course of study.

3 In order to comfortably succeed in MAT 113 you will need to be proficient in the following skills. If you need to brush up on any of these skills please ask for help immediately! o Basic equation solving o Solving application problems o Evaluating exponential expressions o Factoring all types o Simplifying rational expressions GRADES: The course grade will be determined as follows: Component Possible points Weighted Percentage 4 Tests % MyMathLab Homework (14 assignment 5 points each) 70 14% 4 Quizzes and/or projects % Final examination % TOTAL % Letter Grade Percentage A 90% - 100% B 80% - 89% C 70% - 79% D 65% - 69% F Less than 65% Tests: At the end of each module you ll take a test. You are not allowed to use notes or textbooks for tests. Don t forget to bring a pencil, and a calculator. If you missed a test for any reason, you have a zero for that test. Final exam is a comprehensive exam. Everyone must take it in class. MyMathLab assignments: You are expected to do homework problems in MML. This may help you to check whether you had understood the information from each lesson.

4 Projects: Throughout the semester you will have at least 4 projects/writing assignments and or quizzes. Attendance and Participation: Research shows that attendance is the single most important factor in school success. Students are expected to attend each class, arrive on time, complete all assignments and learning assessments in accord with the syllabus schedule, and participate in the in-class learning process. Learning builds day by day. If you miss a day of class, you miss a day of learning. Material learned on one day is used the next day and the next day, and so forth. It is very difficult to catch up when you miss one day and fall behind. It is the student s responsibility to make up any work missed due to an absence for any reason. Classroom Etiquette: It is assumed that all students will respect each other s rights to fully participate in the discussion of the day. To that end, it is expected that students will not engage in behaviors that distract not only the instructor but also their fellow classmates. Students who engage in activities such as talking to each others, talking on cell phones or text messaging, leaving class for non-emergency needs, will be asked to leave. If you are unlucky enough to be one of these students, you will be required to meet with me in my office prior to returning to class. I expect that all of students will behave in an adult, respectful and polite manner towards both the instructor and their classmates. Students are prohibited from using, activating or displaying personal electronic devises. Learning Outcomes: Students will be able to: 1. Use appropriate algebraic problem solving tools to solve equations and/or inequalities 2. Use the rectangular coordinate system to construct graphs of given functions, and a graphing calculator to verify the graphs. 3. Algebraically and graphically analyze the characteristics of polynomial, rational, exponential, and logarithmic functions. 4. Solve systems of linear and/or non-linear equations by the methods of substitution, addition, Gaussian elimination and/or Cramer s Rule as appropriate to the problem. 5. Apply various methods of algebra to problem solving of applications and use a graphing calculator to verify the calculations and/or graphs.
