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.

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.

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.

1. Compute with Linear, quadratic, rational functions. Including solving equations involving such functions.
2. 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).
3. Use functions as models for business application problems.
4. Compute with simple interest, compound interest, and continuously compounded interest models.
5. Evaluate exponential functions and be able to solve equations with exponential expressions using logarithms.
6. Find the derivative of a polynomial function and evaluate marginal revenue/cost/profit for a revenue/cost/profit function
7. Explain verbally and in writing why maximum profit is realized when marginal revenue equals marginal costs.
8. Use derivatives to find local maximum and local minimum points.
9. Solve a system of linear equations using algebraic (elimination) methods, and use them in business applications.
10. Understand basic Matrix operations and use them in business applications.

1. Represent, understand, and explain mathematical information symbolically, graphically, numerically, and verbally;
2. Develop mathematical models of real-world situations and explain the assumptions and limitations of those models;
3. Use models to make predictions/draw conclusions/check whether results are reasonable/find optimal results; using technology when necessary and appropriate;
4. Demonstrate an understanding of the nature of mathematical reasoning including the ability to prove simple results and/or make statistical inferences.

1. Functions: Definition and concept; graphs of functions and equations; Linear, quadratic, square and cubic root, general polynomial, absolute value, rational, exponential, logarithmic.
2. Business applications of the above functions: cost, price-demand, revenue, profit.
3. Mathematics of accounting and finance. Simple interest, compound interest, continuously compounded interest.
4. The derivative: Limits, continuity, difference equations, computing the derivative with the limit, computing derivative of the above functions and their compositions.
5. The derivative and applications to business: Maximum profit is realized when marginal revenue equals marginal costs, elasticity of demand and connection to revenue.
6. Systems of linear equations and applications.
7. Matrices and equations.

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 announced
  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 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 provide 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.

Is required and your grade will be penalized if you miss too many classes. Remember to sign the sign-in sheet every class.

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.

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.
