Second Course in Algebra Webster Wells

Special attention is directed to the emphasis placed upon getting roots of quadratic equations in decimal form. (S ee 78.) (c) Chapter IX is an elaboration of Chapter XVI of the First Year A lgebra. The advantage of postponing the topics in this chapter until well into the third semester of algebra is apparent. I solating these topics as in this text makes it possible for schools that desire a brief course to omit the chapter altogether. In this chapter, topics such as those in 89 to 95 find a logical place. (d) The remaining chapters contain the topics which appear among the various college entrance requirements in algebra. In the main, all colleges enumerate the topics considered inC hapters I to XIV. The other topics are enumerated by one or more institutions. Obviously, teachers will need to select the chapters that meet the needs of their classes. (e) Special attention is directed to Chapters XIII and XIV, onE xponents andR adicals. These chapters, while of considerable mathematical interest, probably are retained in secondary courses largely because they appear among college entrance requirements. Usually they are taught in the first course. They are so difficult that students acquire there little knowledge and very little skill in dealing with them. Where preparation for an examination is a special aim, the authors are confident that instruction on these topics toward the latter part of the third semester of algebra will be found not only more pedagogical but more timely. The examples selected for this text are as simple as possible. More difficult examples onE xponents occur in the supplementary set F. Attention is directed to the practical turn given to radicals in 126.
