Homework
All homework is to be completed on Webassign. You are responsible for
keeping track of all assignments and their due dates. Solving homework
problems will help you to understand the key concept and to master
the skills you will need to succeed in this course. You should try to
work on the problems assigned for a section as soon as the material is
covered. You may discuss problems with other students, but all submitted
work should be your own.
Go to www.webassign.net and use the code
unr 9970 2564
You will be asked to set up a Webassign account
if you do not already have one. Please use exactly the same name
and email you use to register for courses at UNR.

Equal Opportunity Statement
The Mathematics Department is committed to equal opportunity in
education for all students, including those with documented physical
disabilities or documented learning disabilities. University policy
states that it is the responsibility of students with documented
disabilities to contact instructors during the first week of each
semester to discuss appropriate accommodations to ensure equity in
