Required Text: Precalculus 3^rd Edition by Sullivan & Sullivan III,

Optional Text: Students’ Solutions Manual for Precalculus

Check out the Solutions manual for this course before purchasing it to see if the book meets your needs. There is a copy in the library and a copy in the Gateway Math Center.

Course Description: This course covers exponential and logarithmic functions, conic sections including circles, parabolas, ellipses and hyperbolas. We will study linear systems, matrices, linear programming, sequences and series, mathematical induction and the Binomial Theorem. Special emphasis will be placed on application problems and the use of the Texas Instrument 89 (TI89) graphing calculators. This course will connect math with the “real” world.

Prerequisite: A grade of “C” or better in Math 154 or equivalent or appropriate skills demonstrated through the Math Assessment process.

As a courtesy to everyone in class, please turn off all cell phones.

Students with disabilities must identify themselves to me within the first two weeks of class.

Accommodations for Students with Disabilities: Students requiring accommodations for a certain disability that may affect class performance are requested to schedule with a staff member at the DRC to discuss this during the first week of the quarter so that appropriate arrangements can be made.

Course materials are available in an alternate format.

The Gateway Math Center has free tutoring for all registered students. Please Log In and Out so that the facility gets the funds it needs. I recommend students have a study buddy and/or work in groups.

In this class, it is your responsibility to drop the class in order to avoid an unwanted grade.

You must go to Admissions & Records.

Friday, January 14, 2005 is the last day for refunds.

Friday, January 28, 2005 is the last day to drop with no record.

Friday, March 4, 2005 is the last day to withdraw with a “W” grade.

Student Outcomes
Students will be able to:
1. exhibit a proficiency in the topics covered in the course;
2. engage in logical and critical thinking;
3. read technical information; and
4. demonstrate the solution to problems by translating written language into mathematical statements, interpreting information, sketching relevant diagrams, analyzing given information, formulating appropriate math statements and checking and verifying results.

Grading: Your class letter grade will be based on the usual grading scale:

A: 90% and above, B: 80-89%, C: 70-79%, D: 60-69%, F: 59% and under

Homework (.652)(230 points) 15 %

3 Quizzes (1.222)(90 points) 11 %

3 Midterm Exams (160 points each) 48 %

Comprehensive Final Exam (260 points) 26 %

Total 100 %

*I have given practice problems at the end of the syllabus. These problems are for you to improve your understanding of the material and to prepare you for quizzes and exams. Do some problems from each set after their lectures. I do not collect practice problems.

Homework: The homework problems to be turned in weekly are due on Thursdays. Their due dates are listed every week. These problems are considered late if they are not turned in by 3:30 PM the day they are due. If you will be absent, either turn in the homework early or have someone turn in the homework assignment for you. Homework that is turned in late within one week of the due date receives half credit. Homework turned in after this receives no credit. All homework sections are worth 10 points each except 4.6 & 4.7 are each worth 5 points.

Quizzes: There are no make-up quizzes. I give 4 quizzes but only 3 are counted. The lowest quiz score will be dropped. Each quiz is 30 points. All quizzes are given at the beginning of class. Please be on time.

Midterm Exams: You must notify me before an exam if you will miss the exam (541-4660 EXT 368). Exams must be made up within 3 school days after the scheduled date, with a penalty of 10%. You may take an exam up to 3 school days before the scheduled date without penalty. Arrangements must be made with me one week in advance.

Parts of the testing do not allow the use of a graphing calculator.

A regular calculator is OK.

Please talk to me if you do not understand my policies.
