Cramer's Rule and Determinants:

To study Cramer's rule and how to calculate determinants, I would recommend looking at some square matrices you make up or find in your book.  Try to find the determinant and then check your answer on your calculator.  Also, try to solve some linear systems from previous homework using Cramer's rule.  Since you already have the solution, you will get a good idea of whether or not you are correctly applying Cramer's rule.  

There will not be a quiz tomorrow 9/11/03, since I am just now getting this posted.

Thanks to all the students who found links.  Here they are.
