Instructor: Shaffiq Welji
My campus telephone number is x45881 (212-854-5881), and my office is in Mathematics Building room 408. You can also reach me via e-mail at welji@math.columbia.edu.
Office Hours and Additional Help: Shaffiq's office hours are Mondays and Wednesdays from 11 AM to 12 PM in 408 Mathematics (tentatively). I can be available at additional times by request or appointment. As always, help is available (for free!) in the math department's Milbank Help Room, which is open pretty much all day, every day in room 333 of Milbank Hall on the Barnard College campus (across Broadway from Columbia). A more detailed schedule is available here. There is also paid tutoring available.
Text: The text for this course is J. Stewart, L. Redlin, and S. Watson. Precalculus: Mathematics for Calculus. Fifth edition. Belmont, CA: Brooks/Cole, 2006. (ISBN 0-534-49277-0). The cheapest place I can find the book is on AddAll (http://www.addall.com).
Course Description: This course is intended for students who wish to continue their mathematical studies through calculus. Although the course is not exclusively for such students, preparation for calculus is the primary goal of this course. The secondary goal is to develop problem solving skills which will be useful in any further mathematics course. The focus of the course will be on functions and important examples of functions such as polynomials, rational functions, exponentials, and trigonometric functions.
Most of the material we will cover in class is also covered in the book. We will begin with a (somewhat brief) review of preliminary algebraic and geometric concepts (chapter one). We will spend the majority of the course studying functions (chapters two through seven). We will wrap up the course with a few miscellaneous and useful topics (parts of chapters eight through ten). And we will end the course with an introduction to ideas leading to calculus (chapters eleven and twelve).
Warning:
Grading: The following grading scheme is tentative.
Homework: Homework will be assigned for every class, and assignments are due just before every class. Submit your assignments by 9:00 AM on Mondays and Wednesdays outside of room 407 Mathematics Building to the box labeled "Shaffiq Welji / Precalculus In". Homework will be returned to the box labeled "Shaffiq Welji / Precalculus Out". Late homework will not be accepted under any circumstances. Although homework does not contribute to a large fraction of your grade, it is an essential component of learning the subject. Make sure your homework is stapled with clear, coherent, and organized solutions. No solution will be considered fully correct if it is not clear, coherent, and organized.
Presentation of Problems: This will be discussed in detail in class, but for some preliminary information, see the section labeled Important Course Details above.
Tests: We will have two midterms and one final, which will All test will be announced well ahead of time in the Schedule of Lectures and Homework. No calculators are allowed on any of these tests. In fact, make sure all electronic devices are completely put away during all tests. The final exam will be given according to the registrar's schedule. If you let me know about any test conflicts well ahead of time (at least a week or two), I might be able to make arrangements. However, there will be no make-up tests without a note from a dean.
Collaboration: Although collaboration is encouraged on homework and any more informal circumstances, any work you submit for homework must be your own write-up (which means taking the ideas and notes from the collaborative effort and turning those notes and ideas into coherent, clear explanations). Copying homework will not be tolerated. Any cheating on exams or quizzes will be handled severely.
Notes: The course will be moving quickly. This means that you will have to keep up. In order to help you do this, I have a number of suggestions for how to study. Active participation is encouraged. Please ask me any questions that you have. Mathematics is not a spectator sport, and you cannot learn without questioning and doing exercises. Your work for every class should consist of:
This schedule is tentative. It might change as the class progresses. Please check regularly for changes and updated homework information.
