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. Course Schedule: The
following is a tentative schedule. If
things change (and I have money that says they will), I will let you know. 7
