| Note 1) |
Discussion in class is an important part of working the
assignments. Students must be prepared to discuss the
assignments starting with the class following the "Assigned"
date.
|
| Note 2) |
The text includes "Exercises" embedded throughout the reading
assignments and "Problems" at the end of each chapter. All the
assignments refer to "Problems" at the end of the chapter unless
they are prefixed with "Ex". Example: The first problem
assigned in this class, 1.5, is found on page 42 but Ex1.5 is
found on page 11 (and Ex1.5 is not the assigned problem).
|
| Note 3) |
A "+" mark in front of the problem number means an answer
is given at the end of the text, in Appendix I.
|
| Note 4) |
The letter "D" in front of a problem number indicates a design
oriented problem. The student may need to use some judgement in
understanding what the problem statement is requesting. (Ask
Prof. De Boer if you are in doubt.)
|
| Note 5) |
Asterisks (*) indicate more difficult or more time-consuming
problems (in the authors' judgement). The more asterisks, the
more difficult.
|
| Note 6) |
If the "Returned" date is a link (gold color), then the solution
key is posted on Canvas@dordt. Click on the returned date to
go directly to the solution key.
|
| Note 7) |
Problem sets shown above with no "Assigned" date are tentative.
More problems might be added, expected due dates might change,
but problems shown will eventually be assigned.
|
| Note 8) |
If you are having difficulty reading the latest version of this
page it may have to do with your browser's cached memory. Read
this note on
cached pages to solve the problem.
|
| Note 9) |
If a link brings you to a login page use your Dordt College
network username and password. If this brings you to the opening
page of Canvas@dordt instead of the resource you wanted, click
your browser's back arrow twice to return to the link on this
page, then click the link again. Once you are signed in the
link will work properly.
