Test 2 — Due Nov. 5 at the beginning of class
This exam must be worked on independently. However, you are allowed to
use your notes, the course textbook, and old homework. You are also allowed to
talk to the instructor. You are
not
allowed to use any other books, or to talk to
anyone else about the exam.
Keep in mind that it is very easy to tell when a student has plagiarized a proof. Also keep in mind
that the University of Iowa takes academic misconduct very seriously, and that anyone caught
cheating will receive, at minimum, a failing grade in this course, and will also be reported to the
dean for possible further disciplinary action.
In problems that ask you to compute something, please show your work and
justify any calculations you make.
