This will be done by taking a mathematical rigorous approach to the study of functions of a real variable. While many of the topics will seem familiar from your calculus courses, the focus will not be on concepts that are easily visualized. Most of our work will involve complete understanding of definitions, applying them in contexts where simple intuition will fail, and extensive use of formal proofs as communication. Text: Understanding Analysis, by Stephen Abbott Homework: Daily homework assignments will be collected and graded. Attendance: Attendance is critical to the understanding of the material in the course; it is both required and expected. Any absence that is not discussed with the instructor prior to the missed class is considered unexcused. Unexcused absences may result in the lowering of the final grade. I will assume that if you accumulate 3 unexcused absences you are not interested in completing the course and will drop you from the class (DF). When absent, excused or unexcused, you are responsible for all material covered in class. You will not be allowed to make up any work missed due to an unexcused absence. MCSP Conversations: The Math, Computer Science and Physics department offers a series of discussions that appeal to a broad range of interests related to these fields of study. These co-curricular sessions will engage the community to think about ongoing research, novel applications and other issues that face our discipline. Members of this class are invited be involved with all of these meetings; however participation in at least three of these sessions is mandatory. After attending, students will submit within one week of the presentation a one-page paper reflecting on the discussion. This should not simply be a regurgitation of the content, but rather a personal contemplation of the experience. These writeups will be counted as quizzes. Quizzes: Quizzes will be given frequently and randomly, serving both as an incentive for the student to keep up, and as a gauge for the instructor to measure the students understanding of the material. Tests: Two tests will be given throughout the semester. Final Exam: The final exam will be cumulative, covering all material presented in the course. Grading: A students grade will be determined as Two Tests 25% each , Quizzes & Homework 25%, Final Exam 25% No test or quiz scores will be dropped when calculating averages. A tentative guideline for determination of grade will then be: A AB+ > 93 90 – 93 87 – 89.9 B BC+ 83 – 86.9 80 – 82.9 77 – 79.9 C CD+ 73 – 76.9 70 – 72.9 67 – 69.9 D DF 63 – 66.9 60 – 62.9 < 60 Attendance and class participation will be considered when determining marginal and plus or minus grades. Academic Integrity: Students are expected to adhere to the Academic Integrity policies of Roanoke College. All work submitted for a grade is to be your own work! No electronic devices other than the TI-89 can be taken out during any class or testing period.
