Required Text: Precalculus 4^th 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 your 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 available in 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 getting a study buddy and working 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, Jan. 12, 2007 is the last day for refunds.

Friday, Jan. 26, 2007 is the last day to drop with no record.

Friday, March 2, 2007 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.

Academic Integrity:

Homework may be done in groups with other students or with the help of the instructor or tutors, but each student must turn in their own work.

Quizzes and Exams must be done by the student alone.

Any Student who violates this rule will receive a zero on the Quiz or Exam.

A second offense will result in withdrawal or failing the course.

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 (.583 of 240) 140 15.05%

4 Quizzes @ 35 pts each 140 15.05%

2 Midterm Exams @ 200 pts each 400 43.0%

Comprehensive Final Exam: 250 26.9%

Total 930 100.0%

Homework: The homework problems to be turned in weekly are due on Wednesdays. Their due dates are listed every week. These problems are considered late if they are not turned in by 5:00 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 by the next class meeting receives 70% credit. Homework turned in one week late of the due date receives half credit. Homework turned in after this receives no credit. All homework sections are worth 10 points each except sections 4.8 & 4.9 are worth 5 points each.

Quizzes: There are no make-up quizzes. I give 5 quizzes but only 4 are counted. The lowest quiz score will be dropped. Each quiz is 35 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 come talk to me if you do not understand my policies.
