This site contains reference material in Matrix Algebra. Topics covered include matrix operations, linear equations, determinants, eigenvectors and eigenvalues. S.O.S. Mathematics--Matrix Algebra is a part of an independent, commercial site that offers straightforward technical assistance primarily to high school and college students.
Type of Material:
Reference and tutorial.
Identify Major Learning Goals:
To serve as reference in the algebra of matrices or as a supplement for a standard course in Linear Algebra.
Target Student Population:
Students studying linear algebra and matrices.
Prerequisite Knowledge or Skills:
Evaluation and Observation
This is a straightforward introduction to the matrix-related topics found in typical Linear Algebra courses. This learning resource does a good job of motivating some concepts that other texts often leave as mere definitions, like matrix multiplication (an application precedes the definition) and determinants of order higher than two (a set of defining properties is determined from the 2 X 2 case).
Potential Effectiveness as a Teaching Tool
This site could be of significant benefit to students who would like a supplement to their text in a Linear Algebra course. The presentation is brief, and the writing is clear and concise. Concepts are often motivated better than in many mainstream texts. A number of examples scattered throughout will aid student understanding.
Exercises with solutions would significantly improve the effectiveness of this site.
Ease of Use for Both Students and Faculty
This learning resource is easily navigable. The topics are well-organized and all the key concepts are properly emphasized. Commercial advertising is somewhat distracting in places, but the layout is otherwise clean and simple, with good displays of mathematical formulas that load acceptably fast.
