Klappentext Describing two cornerstones of mathematics! this basic textbook presents a unified approach to algebra and geometry. It covers the ideas of complex numbers! scalar and vector products! determinants! linear algebra! group theory! permutation groups! symmetry groups and aspects of geometry including groups of isometries! rotations! and spherical geometry. The book emphasises the interactions between topics! and each topic is constantly illustrated by using it to describe and discuss the others. Many ideas are developed gradually! with each aspect presented at a time when its importance becomes clearer. To aid in this! the text is divided into short chapters! each with exercises at the end. The related website features an HTML version of the book! extra text at higher and lower levels! and more exercises and examples. It also links to an electronic maths thesaurus! giving definitions! examples and links both to the book and to external sources. Zusammenfassung This text gives a basic introduction and unified approach to algebra and geometry! two of the cornerstones of undergraduate mathematics. The emphasis is constantly on the interaction between these topics. For ease of use by students! the text is divided into short chapters! with exercises at the end of each.
