Mth 306 Documents

Last updated March 07, 2008

This page lists notes, sample problems, etc., for Mth 306. You may find this material useful for studying.

Many of the documents are in Portable Document Format (PDF) or are Maple worksheets (MWS). PDF files are "Portable Document Files." You can use the free Adobe Acrobat Reader, available at http://www.adobe.com, to view or print PDF files. The Acrobat Reader plug-in is installed in the browser(s) on many campus computers. There are many other software packages for reading PDF files.

Problems viewing or printing PDF files. Please report any problems you have reading or printing my PDF files.

For some of the tests and sample problems below I have listed the answers. When creating a list of problems I often edit the problems several times but forget to edit the answers! I make a careful list of answers for grading purposes, but that list is often lost. Other errors occur too. So take my suggested answers with a very large grain of salt and check your answers, especially if we disagree.

2005 Winter Mth 306 Matrix and Power Series Methods Sample Problems I
PDF, 44 KB, 5 pages, 16 problems with solutions

Answers: (Answers are included in the document). Our test will be mostly, or all, multiple-choice. However I didn't formulate any of the sample problems as multiple-choice problems because of the extra time required. I have provided solutions to these problems. You should not look at the solutions before your forehead is bloody from beating it against the problems! You should not trust the solutions - I might have spaced off and made errors. Try to find ways to check your own solutions. It's a valuable skill.
