Don't drop by the office that the Math Department has listed for me: I will never be there so
you will be wasting your time.

| Telephone: |
626-395-8161 - Don't abuse it, please! If you leave a message tell me who you are and why you are
calling, being specific. I ignore phone messages like "This is Joe for 103, I wanted to ask you
something."
Don't call the number the Math department lists for me. I don't use that telephone and I don't
check the messages there (ever).
In any case you are more likely to reach me a lot more quickly by email.

| Catalog Description |
| Prerequisites: Passing score on or exemption
from the Entry Level Mathematics Examination (ELM), or credit in Math 093 and a passing score
on the Mathematics Placement Test. Concepts and applications of algebra and calculus to
business. Topics included functions, systems of equations, matrices, the derivative and
business-related topics in calculus. (Available for General Education, Mathematics) |
|
Lab Class
Math 103L: |
All students must concurrently enroll in Math 103L unless you have a score of 24 or higher on
the MPT.
If you are required to take the laboratory class and do not, you will be dropped fromt this
section of Math 103.
Students who are required to take Math 103L must complete the online portion of Math 103L by the
8th week of class. You lab instructor will verify that you have satisfactorally completed this
assignment.
|
| Course Objectives: |
Upon completing this class, the student should be able to:
- Compute with Linear, quadratic, rational functions. Including solving equations
involving such functions.
- Prepare a well-scaled graph of a one-variable function, e.g. find the equation of a
linear function from two ordered pairs, graph a quadratic function, or graph
(3x+5)/(2x-3).
- Use functions as models for business application problems.
- Compute with simple interest, compound interest, and continuously compounded interest
models.
- Evaluate exponential functions and be able to solve equations with exponential
expressions using logarithms.
- Find the derivative of a polynomial function and evaluate marginal revenue/cost/profit
for a revenue/cost/profit functionn
- Explain verbally and in writing why maximum profit is realized when marginal revenue
equals marginal costs.
- Use derivatives to find local maximum and local minimum points.
- Solve a system of linear equations using algebraic (elimination) methods, and use them
in business applications.
- Understand basic Matrix operations and use them in business applications.

| General Education Student Learning Outcomes: |
Upon completing this class, the student snhould be able to:
- Represent, understand, and explain mathematical information symbolically, graphically,
numerically, and verbally;
- Develop mathematical models of real-world situations and explain the assumptions and
limitations of those models;
- Use models to make predictions/draw conclusions/check whether results are
reasonable/find optimal results; using technology when necessary and appropriate;
- Demonstrate an understanding of the nature of mathematical reasoning including the
ability to prove simple results and/or make statistical inferences.
Student Learning Outcomes (1) through (4) will be assessed via the student's performance
on midterm and final exams.

| Topics Covered: |
- Functions: Definition and concept; graphs of functions and equations; Linear,
quadratic, square and cubic root, general polynomial, absolute value, rational,
exponential, logarithmic.
- Business applications of the above functions: cost, price-demand, revenue, profit.
- Mathematics of accounting and finance. Simple interest, compound interest, continuously
compounded interest.
- The derivative: Limits, continuity, difference equations, computing the derivative with
the limit, computing derivative of the above functions and their compositions.

Grading Policy:
|
The final grade will be calculated as follows:
- 30% - Final Exam - Saturday, December 13, 11:30 AM - 1:30 PM
The exam will be in Location to be announcend
Note: if you miss the final exam you will automatically fail the class.
- 20% - Homework
- 50% - Three in class exams (18 Sept., 16 Oct., 13 Nov.).
The lowest of the three will count 10%, the others 20% each
Exams must be taken at the scheduled times - no makeup or advance exams will be given.
If you are unable to take the final exam at the scheduled time you should drop this class now.
The date and time is set by the University and cannot be changed for any reason.
|
Homework
Policy: |
Homework is an integral part of this class. If you don't do the homework you can expect to fail
the exams.
Homework assignments will be completed using Webwork. The computer will
automatically grade your problems and provinde you with interactive feedback automatically.
Occasional assignments, such as plotting, will be done on paper, and must be turned in to me on
paper on the assigned due date.
Your webwork username and password will be discussed in class.
|
|
Attendance:
|
Is required and your grade will be penalized if you miss too many classes. Remember to sign the sign-in sheet every class.
|
|
Adding the class:
|
The class is full. If any students drop the class
and space becomes available additional students may be allowed in on the second week of classes (but
not before that). I will not send out permission numbers by email. |

Textbook:
|
 College Mathematics for Business, economics, life sciences and social
sciences, Second Custom Edition for California State University, Northridge By Raymond A.
Barnett, Michael R. Ziegler, and Karl E. Byleen, Pearson Custom Publishing.
This edition of the text only has chapters 1 - 4 and 10 - 12.
Note that we will not cover the entire text, and those sections that we do cover will not be
followed in linear order through the book. We will cover the following sections (in this order):
1.1, 1.2, 2.1, 2.2, 2.3, 3.1, 3.2, 2.4, 2.5, 10.1, 10.2, 10.4, 10.5, 10.7, 12.5, 12.6, 11.3, 11.4,
11.7, 4.1, 4.2, 4.3, 4.4, 4.5.
See the Class Schedule for approximate dates that these sections will
be covered. You are expected to read the assigned sections of the text before coming to class.

I encourage students to bring snacks to share with me and the
rest of the class. |

Student Conduct
|
Students are expected to conduct themselves in accord with university policies on Student
Conduct and Academic Dishonesty. Violation of this code could be punishable by a failing grade in
the class or removal from the university, as determined by Dean of Students.
I require students to sign an affirmation that they will abide by the
student conduct code (and not cheat in this class) and to reaffirm this contract at each exam. If
you are uncomfortable signing this affirmation you should not enroll in this section of Math
103.
The student conduct code is posted at: http://www.csun.edu/a&r/soc/studentconduct.html
and is in the University Catalog, Appendix C.
