TEXT: Barnett, Ziegler & Byleen's PRECALCULUS Fifth Ed

CONTENT: Chap 1 - Equations
Chap 2 - Graphs & Functions
Chap 3 - Polynomial & Rational Functions
Chap 4 - Exponential and Logarithmic Functions
Chap 8 & 9 ?? We'll see.

EVALUATION:

4 - 100 POINT TESTS Jan. 26, Feb. 16, March 9, April 6
Daily Quizzes worth total of 100 pts which you may use to replace your lowest test grade
1 - 200 POINT FINAL, Final ExamThursday May 4

Perspective from the instructor:
Up to this course, the primary objective of your study of algebra has been to learn symbols, definitions and operations in algebra. We will introduce a few more definitions, symbols and operations in this course, specifically: function notation, operations on functions, exponential and logarithmic functions, complex numbers, operations on complex numbers, systems of equations. But we also examine new ideas algebra was used to discover or examine more thoroughly: the Fundamental Theorem of Algebra, it's applications to solving polynomial equations.
In spite of all this exciting new content, the prevailing objective of this as well as any other math course is to learn the language of math, which requires working lots of problems requiring use of new concepts and lots of old algebra. This course has been designed to engage you adequately in the material to accomplish this objective.

The above total is 600 points, and your accumulative total will be divided by that amount to calculate your final percentage, which determines your final grade. Quiz average may replace your lowest test score.

GRADES: 90 - 100 = A, 80 - 89 = B, 70 - 79 = C, 60 - 69 = D

NOTES:

1. No make up tests will be given, a missed test will be replaced by 1/2 your final exam score.

2. Final percentages will be rounded up. i.e. 79.00001 will be rounded up to 80 . Tentative DAILY SCHEDULE
