Textbook: Precalculus: A Prelude to Calculus, First Edition, by Sheldon Axler.
- Please be sure to buy the first edition (which has a grey cover), not the newer second edition (which has a red cover).
- You can get a significant discount (more than half off!) if you purchase the textbook through the Wiley direct-to-student site: http://www.wiley.com/WileyCDA/Section/id-811889.html

Enrollment: Unfortunately, I do not have control over the course roster. If you are waitlisted or need to switch sections, you have to wait for something to open up and make the change yourself on Telebears. You may only switch into a section with free seats, and you must attend the section for which you are registered.

Assignments and Grading: Your grade for the course will be based on homework and quizzes, two midterms, and a final.

10% - Homework
20% - Quizzes
20% - Midterm 1
20% - Midterm 2
30% - Final Exam

Homework: Homework is due most Wednesdays (see schedule). Hand it in to your GSI at the beginning of section self-graded (see below).
Your lowest homework score will be automatically dropped at the end of the semester. No late homework will be accepted.
Self-grading policy: When you hand in your homework, write a whole number (no half points) 1-3 clearly at the top of the first page.
0: You'll get a 0 if you don't turn the homework in.
1: I only did a small number of problems, or I put very little effort into the homework.
2: I put some effort into the homework, but I skipped some problems.
3: I made a serious attempt at all of the problems.
Please be honest. The difference between a 1, a 2, and a 3 will be quite clear to your GSI.

Quizzes: Quizzes will be given in section most Wednesdays (see schedule). Quizzes will be 10 minutes long, will be graded out of 6 points, and will consist of two questions taken directly from the homework.
Your lowest quiz score will be automatically dropped at the end of the semester. No make-up quizzes will be given.

Exams: The midterm exams will be 50 minutes each, held in class on Friday 3/1 and Friday 4/5. The final exam will be 3 hours, held Monday 5/13 8-11am in Hearst Gym, Room 220.
Please be sure you can attend the exams! No make-up exams will be given for any reason. However, if your (percentage) score on the final is better than your (percentage) score on one of the midterms, your lowest midterm score will be automatically replaced by your score on the final at the end of the semester.

A note on calculators: No calculators (or cheat sheets) will be allowed (or necessary!) on quizzes or exams. I will avoid assigning homework problems which require a calculator, but you may sometimes find that a calculator is useful for checking your work or doing a decimal approximation. If you don't have a physical calculator, I recommend Wolfram|Alpha, which knows a surprising amount of math.

Where to get help: This course will be challenging! Here are some resources.

  • Section. The purpose of section is to help you do well in the class! In addition to giving you more practice with the material, your GSI will be happy to answer your questions and work through problems on the board, as time allows.
  • Office hours. Office hours are a great place to get one-on-one attention from the GSI or the instructor. We will talk you through problems, explain tricky concepts, or just chat about the course.
  • The Student Learning Center. The SLC offers drop-in tutoring Monday-Thursday 10-4 in Chavez 103. Information is available at http://slc.berkeley.edu/math_stat/index.htm.

    Special arrangements: Some of the grading policies above may be adjusted in the case of extended medical absence.
    If you have special testing arrangements through DSP, talk to me as soon as possible. I will need at least a week to set up alternative testing arrangements.

    Schedule: The course consists of three units, loosely organized around three classes of functions.

  • Functions and algebra. Weeks 1-6 (culminating with Midterm 1). We'll start by talking about the real numbers, the properties of arithmetic, and how to solve equations and inequalities. Then we'll study the general theory of functions, introducing inverse functions and examining the relationship between a function and its graph. Finally, we'll focus on algebraic functions: linear functions, quadratics, polynomials, and rational functions. This is Chapters 0, 1, and 2 of the text.
  • Exponents and logarithms. Weeks 7-10 (culminating with Midterm 2). We'll study the exponential functions and their inverses, the logarithms. In particular, we'll see how exponentials and logs appear in various mathematical models. After a digression about computing area in the plane and a preview of calculus by way of estimating areas under curves, we'll introduce the number e and the natural logarithm. This is Chapters 3 and 4 of the text.
  • Trigonometry. Weeks 11-14 (culminating with the Final). This subject brings together properties of circles, right triangles, areas, and distances in a beautiful way. It also introduces us to a third class of functions, the trig functions. We'll define sin, cos, tan, etc., study their relationships by proving trig identities, and use them to solve geometry problems. This is Chapters 5 and 6 of the text.

    The lecture schedule is approximate - we may get ahead or behind. But the assignment due dates and exam days will not change.

    Practice Exams / Resources:

    Note: In Fall 2012, we did not cover rational functions before Midterm 1, so this topic appears on the practice second midterms, instead of on the practice first midterms. This semester, rational functions will be covered on Midterm 1.
