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. (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, 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. Now that you are signed in the link will work properly.
