The official textbook for the course is the 11th Edition of Algebra & Trigonometry by Sullivan published by Prentice-Hall (Pearson). You automatically get an online version of this textbook through Canvas, although you can use a print version instead if you like. This comes with access to Pearson MyLab, integrated into Canvas, on which many of the assignments appear.

Final exam

There will be a comprehensive final exam at the end of the term. (You'll arrange to take it sometime from April 29 to May 5.) To speed up grading at the end of the term, the exam will be multiple choice, with no partial credit.

For the exam, you may use one sheet of notes that you wrote yourself; please take a scan or a picture of this (both sides) and submit it on Canvas. However, you may not use your book or anything else not written by you. You certainly should not talk to other people! Calculators are allowed, although you shouldn't really need one, but not communication devices (like cell phones).

The exam will consist of questions similar in style and content to those in the practice final exam (DjVu). The practice final exam counts as a problem set, so be sure to attempt it and let me know how you did.

The final exam will be proctored. If you have access to a computer with a webcam, then you can schedule a time with me to take the exam in a Zoom meeting. If you're near Lincoln, then we can schedule a time for you to take the exam in person. You can also take it in the Testing Center on the main Lincoln campus or in Beatrice or Milford. If none of these will work for you, then contact me as soon as possible to make alternate arrangements. When it's scheduled, you can take the exam on Canvas.
