CHAPTER
Additional Topics
I N T R O D U C T I O N : In this chapter we shall see how some of the topics that we have studied in earlier chapters can be
applied to other areas of mathematics, such as differential equations, analytic geometry, curve fitting, and Fourier series. The
chapter concludes by returning once again to the fundamental problem of solving systems of linear equations . This
time we solve a system not by another elimination procedure but by factoring the coefficient matrix into two different triangular
matrices. This is the method that is generally used in computer programs for solving linear systems in real-world applications.
