We are almost finished with a unit in my preCalculus for Seniors class. We did Chapter 11 on Matrices in the Sullivan & Sullivan text pictured above. After reviewing the Elimination Method and Points of Intersection for Linear-Linear Systems. We had a lot of fun with Augmented Matrices, Cramer's Rule and Matrix Algebra. We even did some nonLinear Systems and next week we will do Linear Programming to finish up the chapter. Enjoy!
Well, that's all folks!
