[19-Jan-2024] Welcome Spring 2024
I am looking forward to seeing you starting the first week of class.
Mathematics 310 is the first course in
the UNR mathematics curriculum where the emphasis is on mathematical
proof and reasoning. This course focuses on a rigorous justification
of the topics covered in Mathematics 181-283 and provides a stepping
stone to higher-level mathematics.
There will be homework assignments and quizzes weekly.
Mathematical proofs should be carefully written using complete
English sentences, proper grammar, spelling and punctuation.
This is a hard course.
Do not come to class if you are sick--even if it's something other than
COVID-19. If you are subject to quarantine because of exposure to a
person who is sick, please stay home.
This section of Math 310 is in person. However, I will live-stream our
class meetings each day at a link available in WebCampus for those who
are sick or unable to attend on a particular day. I will also maintain
an online archive of course materials including lecture notes,
assignments and other announcements.

make-up exam. If you know that you will miss a scheduled exam please
let me know as soon as possible.
Plagiarism
Students are encouraged to work in groups and consult resources outside
of the required textbook when doing the homework for this class. Please
cite any sources you used to complete your work including Wikipedia, other
books, online discussion groups as well as personal communications. Exams
and quizzes, unless otherwise noted, will be closed book, closed notes
and must reflect your own independent work. Please consult the section

This course is designed to comply with the UNR Core
Objective 10 requirement on diversity and equity. More information about
the core curriculum may be found in the UNR Catalog
here.
Statement on Academic Success Services
Your student fees cover usage of the University Math Center, University
Tutoring Center, and University Writing and Speaking Center. These
centers support your classroom learning; it is your responsibility to
take advantage of their services. Keep in mind that seeking help outside
of class is the sign of a responsible and successful student.
Equal Opportunity Statement
The University of Nevada Department of Mathematics and Statistics
is committed to equal opportunity in education
for all students, including those with documented physical disabilities
