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 is a comprehensive final exam at the end of the term. (You'll arrange to take it some time May 1–5.) To speed up grading at the end of the term, the exam is multiple choice and filling in blanks, 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 consists of questions similar in style and content to those in the practice exam on MyLab. To take the practice exam (which counts as a Problem Set in your grade), hit Next in the bottom right corner (now available). (The first question on the practice exam is a placeholder question that won't count toward your grade.)

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. If you're near any of the three main SCC campuses (Lincoln, Beatrice, Milford) and available on a weekday, then you can schedule the exam at one of the Testing Centers. If none of these will work for you, then contact me as soon as possible to make alternate arrangements. To take the actual exam online, hit Next twice (not available until scheduled). (One of the questions on the final exam is an obvious placeholder question that won't count toward your grade.)
