Textbook: Elementary Analysis by Kenneth Ross, second edition
Using the above link, you can purchase a paperback copy for $24.99 and download a PDF version for free.
Do both.


Exams: There will be two midterms and one final exam. The examinations will be closed book and closed note. There will be no retaking or rescheduling of exams under any circumstances, as the grading scheme allows you to drop your lowest midterm score.

First Midterm: Tuesday, October 23rd, 9:30-10:45AM
Second Midterm: Tuesday, November 13th, 9:30-10:45AM
Final Exam: Tuesday, December 11th, 8:00-11:00AM


Homework:
• Homework assignments will be posted on this website and collected during lecture.
• Only problems marked with an asterisk (*) should be submitted for grading.
• At least one problem on each of the exams will be chosen from the non-asterisked homework problems.
• No late homework will be accepted.
• Homework 1, 2, and 3 will be used as a measure of class attendance and must be turned in.
• The lowest two homework grades will be dropped and will not count toward the final grade.


Grading Scheme: homework: 10%, highest midterm score: 40%, final: 50%
If you have questions about the grading of any assignment or exam, you have one week after it is handed back to request a regrade.

Extra Credit Math Movie Competition:
As an opportunity for extra credit, we will hold a math movie competition. The goal is to make the best math movie, lasting three minutes or less. Submissions are due on Thursday, November 29th. The winner of the competition will receive ten points of extra credit on their final exam. Second place will receive five points of extra credit, and third place will receive three points of extra credit.

Submissions should be uploaded to YouTube, Vimeo, or a similar site. Links to the movies can be emailed to me. (Please do not send the movies as email attachments.)

• Sequences and time series analysis in mathematical finance
• Uncountability of the real numbers
• The history of the real numbers
