General Course Info

Overview This is an introductory course to proof-based mathematics. We will be interested in understanding the rigorous foundations of single variable calculus, in particular, properties of the real numbers, limits, continuity, differentiation, and the Riemann integral.

Office My office is 446 in the Mathematical Sciences building.

Office hours Monday 3:00-4:30, Thursday 4:00-5:30, or by appointment.

Text The textbook for this class is Elementary Real Analysis: Second Edition (2008) by Thomson, Bruckner, and Bruckner.
The text is available for FREE as a pdf download (
click here).
A paperback copy may be ordered from CreateSpace or Amazon for $33.95.

Academic calendar For ease of reference, here is a link to the academic calendar detailing all breaks, add/drop deadlines, etc.

Accommodations In this mathematics course accommodations are managed between the instructor, student, and DRC Testing Center. Students should see instructors outside class hours before or after class or during office hours to share your Accommodation Memorandum for the current semester and discuss your accommodations as soon as possible.

Exams There will be four exams, the first three in class and the last during the final exam period. (See below for schedule and further details.) One exam will be dropped. Please contact me as soon as possible when you become aware of any exam conflicts or if you have missed an exam.

Homework There will be weekly homework sets. (See below for details and due dates.) Students are encouraged to collaborate on homeworks as long as: 1) all collaborators are listed on the cover sheet of each student's assignment; 2) each student turns in their own, individual work. Rote copying of solutions from peers, or plagiarism of any kind, will not be tolerated.

Homework formatting Homeworks must be typed or neatly written on loose leaf paper (no fringes!). There should be no significant cross-outs, rewrites, scratchwork, scribbling, etc. Problems should be clearly indicated and pages must be securely fastened together. Homework should have a cover sheet attached with your name, course section (either 62 or 64), the homework set number, and the names of your collaborators, in that order.

Late homework Late homework will only be accepted if turned in to me in person during office hours. As part of the conditions of acceptance, you may be asked to present your solution of a problem of my choosing. No penalty will be assessed for assignments which are not excessively late (less than one week past due).

Quizzes There will be several quizzes throughout the semester. Quizzes will be announced at least one class period in advance. At least one quiz will be dropped, maybe more depending on the total number of quizzes.

Grades After drops, each item in a given category receives equal weighting. Your percentage of points earned in each category will be combined into a single score with weighting 60% on exams, 30% on homeworks, and 10% on quizzes. Grades will be assigned based on rank among all students in both sections. For marginal cases, there will be some discretionary leeway in final grade assignment to account for course participation/engagement or extraordinary effort.
