Phone: 494-1945
Email: baumanp@purdue.edu
Office Hours: Monday and Wednesday, 1:30-2:30 pm, or by appointment.

Course Lectures:
MWF 9:30-10:20 in REC 317.

Textbook: The Elements of Real Analysis, Second Edition, by Robert G. Bartle, John Wiley and Sons, 1975.

Syllabus: Most of Chapters I-V in the text.

Recommended Extra Material: Appendix A of the book by Bartle and Sherbert, 4th edition, on Logic and Proofs. (Note that this is not the same book as our textbook.)

Homework will be collected weekly in class on Wednesdays (with some exceptions). No late homeworks will be accepted; however, the lowest homework score will be dropped. The assignments are posted below.

Exams: There will be two midterm exams (in class) and a comprehensive final exam.
-- Exam 1 is on Wednesday, Oct. 4, in class. Open textbook (with no notes in the textbook). Covers Sec. 3-12.
-- Exam 2 is on Wednesday, Nov. 15, in class. Open textbook (with no notes in the textbook). Covers Sec. 14-17, 20, 22.


Course Grade: Your course grade will be computed by the scheme:
Final Score = 22% Homework + 23% Exam 1 + 23% Exam 2 + 32% Final Exam.
