MAT 103B

College Algebra Part II

Winter 2003

 

Instructor: Bruce Armbrust, phone: 541-4660 ext. 314, email: armbrust@ltcc.edu

 

Office Hours: Room A210,             Mon. & Wed.               9:30  - 10:30 AM

Fri.                                     10:00 - 11:00 AM

GMC G4,             Tues. & Thurs.            1:15 - 2:15 PM

And as always, by appointment.

 

Class Time and Location: Tues. & Thurs. 10:00-11:50 AM, E106

 

Textbook: Algebra and Trigonometry, Robert Blitzer

 

Calculator: A graphing calculator is required for this class.  I will be demonstrating with the Texas Instruments-89.  I will do my best to assist with other models, but I promise nothing.

 

Course Description: MAT 103B covers the properties of logarithms and exponentials, conic sections including circles, parabolas, ellipses, and hyperbolas.  It also covers systems of equations and their solution with Gaussian Elimination.  The course finishes with a discussion of sequences, series, permutations, and combinations.

 

Prerequisites: A grade of C or better in MAT153 and MAT154 or appropriate skills demonstrated through the Math assessment process.  MAT 153 may be taken concurrently.

 

Course Objectives:

The successful student will:

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.

 

Course Grade: Your final letter grade will be based on the usual grading scale:

A 90-100%, B 80-89%, C 70-79%, D 60-69%, F 0-59%

The following items will make up the course grade:

Homework:                              150 points

Quizzes:                                 150 points

Exam1 (January 23)

Exam2 (February 13):             450 points

Exam3 (March 6)

Final Exam (March 25):            250 points

 


Homework: Homework will be due the class period after it is assigned.  Homework not turned in at this time will be considered late. You may turn in homework up to one week after it is assigned for half credit.  If all homework is turned in, and no more than two are late, the lowest regular exam score will be dropped. Your homework score will be determined in the following way: up to 5 points for completion and one point each for 5 problems chosen at random to be graded.

 

Quizzes: There will be 7 quizzes given over the quarter.  These quizzes will be designed to help prepare you for the exams, and quiz problems will be taken directly from the homework assignments. Your lowest quiz score will be dropped.  Since one score will be dropped, you may not make up a missed quiz.

 

Exams: All exams will be given in two sections: one portion will allow calculators while the other will not.  If you cannot make it to an exam (final not included), you may take it up to 2 school days prior to the scheduled date with proper arrangements.  Otherwise, the exam may be made up after the scheduled date with a penalty of 10% per day.

 

Registration Information: You must register for this class at the Office of Admissions and Records.  You may drop the class with no penalty or mark on your record on or before January 31.  After January 31, you may drop the class and receive a grade of W until March 7.  After March 7, if you are still enrolled, you will receive a grade of A, B, C, D, F or I.

 

How to Succeed in a Math Class: I am often asked how to successfully pass a math class, and here is my advice:

 

I) Come to every class session.  Be prepared, and plan on participating.

II) Do your homework.  Remember that what I assign is what I consider a bare minimum.  If you need more practice, do it.  Don’t make me be a homework enforcer.

III) Read the book.  You paid good money for it, so you might as well use it.

IV) Make use of available tutors and my office hours.  You will find tutors who know the subject matter in this course at the GMC.

V) Do math every day.  Math is just like everything else: if you don’t practice, you become rusty.

 

Learning Disabled Students: It is important that students who are identified as being learning disabled speak to me about their special needs.  I am more than willing to grant you reasonable accommodations.

 

Academic Dishonesty: Academic dishonesty of any form will not be tolerated.  Students caught cheating on exams or quizzes will receive a score of zero on the assignment for the first offense and a course grade of F for the second offense.  Students may work together on homework assignments (and, in fact, are encouraged to) as long as all students understand the material covered.
