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, May 2nd, 12:30-1:45PM

Second Midterm: Thursday, May 25th, 12:30-1:45PM

Final Exam: Monday, June 12th, 12:00-3:00PM


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.


Prerequisites: Math 8

Homework:


  1. Homework assignments will be posted on this website and collected during lecture.


  1. Only the problems marked with an asterisk (*) should be submitted for grading.


  1. At least one problem on each of the exams will be chosen from the non-asterisked homework problems.


  1. No late homework will be accepted.

  (Talk to me if you transfer into the course partway through the quarter, and we’ll work something out.)


  1. The lowest two homework grades will be dropped and will not count toward the final grade.



Extra Credit Math Movie Competition:


  1. 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 May 30th. 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.


  1. Submissions should be uploaded to YouTube or a similar site. Links to the movies can be sent to me at katy•craig•math at gmail • com. (Please do not send the movies as email attachments.)


  1. Potential topic ideas for inspiration...

    - Why we should celebrate square root of two day on January 4th

    - Why series and sequences are actually the same thing

    - Why sequences are the most important mathematical concept in finance

    - Why real numbers are uncountable

    - The entire history of the real numbers in three minutes

    - Epsilons, deltas, and data science
