Problematic problems.
The following problems have been reported. The code
identifies the particular version of the question. This code
appears on the page that is displayed after submitting an
answer.
To report a problem, use the error
reporting form.
General issues.
- Questions with check boxes generally require that
you select all correct answers in order to have the
question marked correct.
- There is no limit on the number of times that you may
submit answers to your homework. All submissions for credit must
occur by the due date. Once you receive credit for a
question, you will never lose credit for that
question.
- It appears that some of the problems do not display
correctly in Mozilla Firefox running on a Macintosh. The
most commonly reported symptom is that subtraction signs
are missing. If you wish you may try to correct this by
installing
additional fonts. Otherwise, students with a Macintosh should
print out their homework from a Windows machine. (Mathskeller is a
convenient place to do this.) Submitting homework problems
on a Macintosh should not present any difficulty.
Homework C7
- Questions 7 and 8 (all versions). The sums in
the problems should extend from 1 to n, rather than from
0 to n. This typographical error was discovered shortly
before the problems were due and will not be corrected.
Homework A5
-
Questions 3, 5 and 9. The buttons across the top of the
page do not always stay green after you submit
a correct answer. However, once you submit a correct answer to
these, or any, questions, you never lose credit. To
verify that you have not lost credit, you can
check the questions that are marked correct in the table
on the "Submit button page" or by clicking on the
"Homework scores" button on
the main page.
Homework A4
- Question 14. All versions. The question should
ask "...at which x-coordinates is the function f(x)
continuous, left-continuous or right-continuous."
