Reference & Test Preparation, Linear, Algebra & Trigonometry 

As the most widely used text on elementary linear algebra, this book, in its 18th year of publication, has been substantially revised and updated. The most significant changes are in the reorganisation to allow for earlier coverage of eigenvalues and eigenvectors. Additionally, there are major improvements in exposition, some new text material, changes and additions to the exercises, and new supplementary software and computer-oriented course materials. As with previous editions the aim is to present the fundamentals of linear algebra clearly, with basic ideas studied by means of computational examples and geometrical interpretation wherever possible. The material is presented so that it can be understood by both introductory and intermediate level students. The previous edition of this book was published in 1987. - from Amzon
