Print This Problem Battle of the Bands - posted May 31, 2004 The students of Rahkenrole High School are trying to pick which of two bands should play at the end-of-year dance, and they're going to have a vote to decide the issue. The two bands are Cold Day, an alternative rock band, and Phesh, which has more of a jam-band sound. To help the students decide which band to vote for, the school had a mini-concert in which each band played three songs. After the concert was over, some people decided to change their preferences. One-third of those who initially liked Cold Day decided to support Phesh. And one-fourth of those who originally liked Phesh now would vote for Cold Day. When the votes were counted, everybody was surprised. It was a tie! There are fewer than 250 students at Rahkenrole High, and the ratio of male to female voters was 7:6. How many students voted in the band decision? Extra: If the election had taken place before the mini-concert, which band would have won? And by how many votes?

Linear Algebra by Jim Hefferon Mathematics Saint Michael's College Colchester, Vermont USA 05439 My text Linear Algebra is free for downloading, It covers the material of an undergraduate first linear algebra course. You can use it either as a main text, or as a supplement to another text, or for independent study. What's Linear Algebra About? When I started teaching linear algebra I found three kinds of texts. There were applied mathematics books that avoid proofs and cover the linear algebra only as needed for their applications. There were advanced books that assume that students can understand their elegant proofs and understand how to answer the homework questions having seen only one or two examples. And there were books that spend a good part of the semester doing elementary things such as multiplying matrices and computing determinants and then suddenly change level to working with definitions and proofs. Each of these three types was a problem in my classroom. The applications were interesting, but I wanted to focus on the linear algebra. The advanced books were beautiful, but my students were not ready for them. And the level-switching books resulted in a lot of grief. My students immediately thought that these were like the calculus books that they had seen before, where there is material labelled `proof' that they have successfully skipped in favor of the computations. Then, by the time that the level switched, no amount of prompting on my part could convince them otherwise and the semesters ended unhappily.
