# Precalculus Algebra

**Description:**

The goal is to prepare the student for more advanced
coursework in mathematics by developing

an improved knowledge base and suitable study/work habits. Specifically, this
course will require the student to

complete assignments on time, follow instructions precisely, and demonstrate an
ability to: solve linear and

quadratic equations and inequalities, including those involving complex numbers;
provide analytic and graphical

descriptions of linear, quadratic, and higher degree polynomial functions, of
rational functions, of simple

exponential/logarithmic functions, and of piecewise defined functions; solve
simple applications of the preceding

(e.g. max/min problems, exponential growth and decay problems, etc.); solve
systems of linear and non-linear

equations in two variables graphically, by elimination, or by substitution;
solve larger systems of linear

equations using matrices and/or determinants; do a partial fraction
decomposition of a rational function with

known factors; and determine the properties of simple arithmetic or geometric
sequences and series.

**Prerequisite:** MAC1105 College Algebra or equivalent

**Textbook and Supplies:** Algebra and Trigonometry -
by M. Sullivan, Prentice Hall 8^{th} Ed. and access to the

MyMathLab website, Course “petrela34871”,which can be purchased bundled with the
text or with a credit card at

Also needed are scantrons (NCS 4521) and a simple
NON-programmable scientific

calculator (e^x & ln key). The calculator is needed for some homework problems,
but may NOT be used during any

quiz, test, or examination unless specifically authorized by the instructor.

**Lectures:
**meet MWF and are the main presentation of the material in the course. They
include some in-class

quizzes usually focusing on the prior homework BUT also repeating questions handled poorly on prior quizzes

or tests. The OUTLINE/CALENDAR lists the lecture topics (by their textbook sections) and a minimal set of

homework problems the student is expected to do either from the text or on MML where they are listed as

problems 1,2,3, … for each section. Each problem set is followed by a MML administered quiz on that problem

set. This quiz can be taken twice (only the best grade counts) but must be completed by the specified due date.

**Evaluation:**

Unlike the MML quizzes. the in-class quizzes and tests are designed so the
student has to do them

under 'time pressure'. No extra time will be given those who come late or with
an unprepared scantron for a quiz

or test. In addition to the graded (MyMathLab) and in-class quizzes, there will
be four 50 minute unit tests, and a

150 minute final. Just before the Final, each student will be given the
opportunity to make-up ONE unit test

grade. Each student's grade is based on his/her final exam grade (worth 30%),
average of the 4 unit test grades

(worth 40%), average of the in-class quiz grades – with worst two dropped-(worth
10%), and the average – with

worst four dropped - of the MyMathLab graded quizzes (worth 20%). That is,
expressing all grades in percent:

GRADE = 0.1^{*}(in-class quiz
ave) +0.2^{*} (MML quiz ave) + 0.4^{*}((unit test ave) + 0.3^{*}(final exam grade)

This is then translated into a letter grade as per the following:

A for 90 ≤ grade ≤ 100 | B^{+} for 85 ≤ grade ≤ 89 |
B for 80 ≤ grade ≤ 84 |

C^{+} for 75 ≤ grade ≤ 79 |
C for 70 ≤ grade ≤ 74 | D for 60 ≤ grade ≤ 69 |

F for grade ≤ 59 |

There is no general curving of grades and no way to earn extra credit.

**Academic Honesty:** Florida Atlantic University
expects students to be honest .

CHEATERS, and THOSE WHO HELP THEM, WILL NOT BE TOLERATED.
