Section 6.5 Applications of Matrices Optional

Much of this section is optional for test purposes.  However, most of the mathematics is very interesting and it is only due to lack of time that much of it will not be explored fully.

Area of a triangle with given vertices
Cramer's Rule for 2 by 2 and 3 by 3 system. Though this method of solving is a nice numeric system, the easiest system to use is still X = A-1B with matrices, or the rref command on the TI 83.

Review Exercises and Practice Chapter Test

At the end of this chapter and every chapter are the review exercises and the chapter testin the text.  These are completed for you on the CD and also in the solutions manual. As with all the exercises in this course, try to do them on your own first before looking at the given answers and solutions, and remember to post questions on the bulletin board and also to email the instructor if you are having difficulty. Do not start the next chapter until you have mastered the material in this chapter.
