Dr. Chinburg, the Undergraduate Chair for Mathematics, has asked the faculty to remind students of several sources of help. These links are also found on our course guide. One is the general math advising page:

The other is the link to the Math 150 newsgroup. This newsgroup is very underutilized. This is a place where you can post questions and get answers. The questions and answers are open to anyone who looks at the newsgroup. The newsgroups are manned by TA's Monday through Thursday evenings from 9 p.m. to 1 a.m. The TA's will not solve homework problems for you, but they will give suggestions if you are stuck. I try to check the newsgroup occasionally as well. The link below gets you to the main Math 150 web page. From there, click on Netnews.

This assignment is related to

- Lecture 18 - Wednesday, October 21
- Lecture 19 - Friday, October 23

**Reminder:** Exam #3 is Wednesday, October 28. It covers the
course through Chapter 4. See additional information on our Course
Guide. Also see the email message I sent to the class on October
18.

- Go through the worked Sample Problem for Chapter 5, Section 3. This material is found on pages 140 - 141 of the Lab Manual. I suggest that you first try to do the problems using MAPLE on your own. Then compare your solutions with those in the Lab Manual.
- Work through Demonstration #7. (Part of this demonstration will be covered in class on Friday, October 23 (I hope).)

**READING: **Chapter 5 Sections 1 - 3.

**CORE PROBLEMS:** Write up, for your own record, solutions to
the Core
Problems for Chapter 5 sections 1 - 3.

**Solution Error: **Problem 5.1 #33. Be sure to do this one
using MAPLE. You will see that the sketch in the answer section of
the text is inaccurate and that the outer curve is mislabeled. The
outer curve is exp(.05*x), not exp(1.5*x).

**OLD FINAL EXAM PROBLEMS:** Final Exams for the past eight
semesters are included at the back of your Math 150/151 Lab
Manual. For this week's assignment you should work the following
problems from the old final exams:

Fall 1996: |
none this week |

Spring 1997: |
none this week |

Fall 1997: |
none this week |

Spring 1998: |
none this week |
