We have one section to cover this week (week 15), and then our last three
assessments in week 16.
Quiz 8 is due by 11:59pm, Tuesday, April 22: Quiz 8 covers Chapter 8
Exam 4 is due by 11:59pm, Thursday, April 24: Exam 4 covers Chapters 7,
8, Appendix B
The Final Exam is due by 11:59pm, Saturday, April 26:
There are 30 problems on the final exam, 10 problems from Chapters
1, 2, 3, 4, and Appendix A, and 20 problems from Chapters 5, 6, 7,
8, and Appendix B.
The time limit on the final exam is 120 minutes.
Notice that on our resources page, and on our Week 15 and 16 pages, we
have placed an item analysis of each quiz and exam taken so far. This
will give you an idea, for each assessment, which questions were missed
by everyone most often. That can give you more questions to focus on while
you are reviewing for the final exam.
Our last two topics this semester are polar equations and graphs.
Think of polar graphs as instructions for placing points in the plane based on
angle and distance from the origin. For the sake of efficiency, this is the one
time that we will allow you to describe "radius" as a negative number.
Polar equations and graphs give us simpler way to see symmetry in some graphs
where the symmetry is not easy to see in the rectangular (\(xy\)-coordinate)
equations.
We can efficiently convert between graphs in rectangular coordinates and
graphs in polar coordinates directly from the graphs or algebraically using the
relationships \( x=r\cos\theta \) and \( y=r\sin\theta \).
This week you can also begin our review of the most frequently missed problemes
from our previous quizzes and exams. Check out the Item Analysis of all past
quizzes and exams in our handouts section to review the problems that were most
frequently missed.
