Course description:
This course is the first semester of the Calculus Honors sequence developed by the Mathematics Department at the UW. The goal of the sequence is to provide highly motivated and well-prepared students with an opportunity to go beyond the traditional approach to the subject to develop a deeper understanding of this fundamental area of mathematics and to appreciate its power and beauty. The material covers essentially the same topics as the standard first semester calculus course, but the material is discussed in greater depth, and with much more emphasis on mathematical ideas. The course will be challenging, and the student might find it surprisingly different at the beginning. But it is also meant to be a lot of fun and to provide the students with the kind of clear and precise thinking that is characteristic of mathematics and that will be useful for them in almost any subject they pursue.

Textbook: T. Apostol, Calculus, Volume 1. 2nd edition.

Prerequisites: Personal invitation or invitation from the instructor.

Course Content: We plan to cover Chapters 1-6 with part of Chapter 9. Additional topics might be included. The main topics are
• Real and complex numbers
• Integral calculus
• Limits of functions, continuous functions
• Differentiation
• The logarithm and exponential function, inverse trig functions

Evaluation: Course grade will be based on work in the discussion section (20%), two evening midterm exams (20%) and a final exam (40%). The final grade will be computed according to the following scale
A: [100,89), AB: [89,87), B: [87,76), BC: [76,74), C: [74,62), D: [62,50), F: [50,0]
There will be no curving in the class, but the instructor reserves the right to modify the final grade lines.

Discussion section grades consist of homework and quizzes. Attendance in one of the weekly discussion sections is required.
You will not be allowed to use calculators during the quizzes and exams.

Exams:
1st midterm: Wednesday,  October 10, 7:15PM-8:45PM, Social Sciences 6102 review sheet
2nd midterm: Wednesday, November 14, 7:15PM-8:45PM, Social Sciences 6102 review sheet
Final exam: December 18, Tuesday, 12:25PM - 2:25PM, Ingraham 120 review sheet

There will be no make-up exams in the course. If you know that you cannot make it for one of the evening exams then you should contact me ahead of time.

Homework and quizzes: Homework will be assigned every week and it should be handed in at the Wednesday discussion section at the start of the lecture on Thursday (starting with the 2nd week). Your TA will decide how much of the assignment will be graded. Your TA may also decide to give quizzes during the discussion section.
The assignments will contain bonus problems. These will be more challenging than the regular homework and will have flexible deadlines. You will need to present the solution of the bonus problem in person (send me an email to set up an appointment). You may schedule a presentation up to the last week of the semester.

Instructions for the homework assignments:

• Please put the problems in order and staple your homework in the upper left corner.
• Justify your steps. In most cases the numerical answer is the least significant part of the solution, it is much more important to show how you got there.
• You must present an original solution to each problem you are asked to hand in. Cheating/ plagiarism will not be tolerated. Instances of academic misconduct will lead to disciplinary action.
• Please use complete sentences. Your solution should not be just a sequence of equations and formulas.
• Make sure that your presentation is clean. Do not submit solutions with crossed out parts. Recopy problems if necessary.

How to succeed in this course: It helps immensely if you keep up with the material during the semester by reading the textbook and following the lectures. I will post section numbers of the textbook for upcoming lectures, it is beneficial to read ahead.
Although reading the textbook is important, the best way to master the material is through problem solving. This of course includes the homework assignments, but you shouldn't stop there, there are more than enough practice problems in the text book. (If you run out of problems to solve, I'm happy to supply more!)
For some students studying in groups helps a lot, let me know if you need help with setting up a study group.
If you feel lost, do not hesitate to ask for help. I'm available in my office hours (see above) or by appointment. Do not wait until the end of the semester if you think you are in trouble!

Schedule:

The homework assigned in week N is due in the Wednesday discussion section Thursday lecture in week N+1.
