The author of this site endeavours to explain how linear algebra has many applications in a wide range of disciplines, to help students see its uses in the real world.

This MathWorld site explains the technique for finding the determinant using minors. The site also suggests to use this method only on small matrices, giving a link to Guassian elimination for the alternative(larger matrices.) The site...

In this set of questions, students will find the x-intercepts of a polynomial function, factor a polynomial, and determine the number of solutions of a polynomial equation. Questions are multiple choice and true/false; solutions are...

This site, which is provided for by the University of St Andrews, gives a biography of James Sylvester, mathematician. Links to other interesting sites are provided as well.

This lesson explains how the determinant is used for Cramer's Rule.

Using determinants and Cramer's Rule, systems of two and three variables are solved step by step. Several examples are presented to demonstrate how Cramer's Rule is used.
