ma253 ,Fa l l 2007 — Problem Set 1 This problem set is about systems of linear equations and Gaussian elimination. As such, it includes several problems that are here just to help you practice the process. Most of those you need not turn in, but you should do them in order to make sure you have the method under control. So solve all the problems, then write up and turn in those marked with an asterisk. This assignment is due on Wednesday, September 19 . Remember that you should be able to do small row-reductions by hand, but that bigger ones are best done with technology: your calculator, the Linear Algebra Toolkit, or something else. See http://www.colby.edu/˜fqgouvea/253 for more information. 1. Problems from the textbook: a. Section 1 . 1 , problems 5 , 7 , 9 ,* 20 ,* 28 . b.
