Textbook: Precalculus: A Prelude to Calculus, by Sheldon Axler.
You can get a significant discount (more than half off!) if you purchase it through this website:

Note: The book is currently backordered on Wiley. If you don't have the book yet, please find another source as soon as possible!
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.
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 two homework scores will be 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 two quiz scores will be dropped at the end of the semester. No make-up quizzes will be given.
Exams: The midterm exams will be 1 hour each, held in class on Friday 9/28 and Friday 10/26. The final will be 3 hours, held Monday 12/10 7-10pm in 155 Dwinelle. The difficulty of exam problems will be similar to the difficulty of homework problems.
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 replaced by your score on the final at the end of the semester.
No calculators or cheat sheets will be allowed (or necessary!) on quizzes or exams. However, I may provide a sheet with important formulas for the exams, especially in the trigonometry section of the course, where it would be very difficult to memorize all the relevant identities. I will also avoid assigning homework problems which require a calculator.
Where to get help: This course will be challenging! Here are some resources.
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.
