 Suppose that you start at the point (1, 0)

for a total distance of s,
and let θ be s/r.

Quizzes
 Basic trigonometry:
 Date available: April 1 Friday.
 Date due on MyLab: April 4 Monday.
 Corresponding problems sets: 1–10.
 Help allowed:
Your notes, calculator.
(If a question tells you not to use a calculator,
you may still use the calculator to check,
but be sure to give an exact answer.)
 NOT allowed: Textbook, my notes, other people, websites, etc.
 Work to show:
Submit a picture of your work on Canvas,
at least one intermediate step for each result except #3, #7, and #9.
(If a question tells you not to use a calculator,
then be sure that your work
shows how you can solve the problem without using one.)
 Advanced trigonometry:

 Date due on MyLab: April 18 Monday.
 Corresponding problems sets: 11–22.
 Help allowed:
Your notes, calculator.
(In graphing problems,
while you may still use a graphing calculator to check,
you should be able to solve the problem without one.)
 NOT allowed: Textbook, my notes, other people, websites, etc.
 Work to show:
Submit a picture of your work on Canvas,
at least one intermediate step for each result except #1.
(In graphing problems,
be sure that your work
shows how you can solve the problem
without using a graphing calculator.)
 Applications:

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.
