About COLLEGE ALGEBRA, VOLUME 1: Fundamental

This book was written to provide an essential assistance to students who are first being introduced to the fundamentals of Algebra and has been designed to be an excellent supplementary textbook for University and College students in all areas of Mathematics, Physics and Engineering. The content of the book is divided into 9 chapters.In Chapter 1 we present the fundamentals of the theory of Sets, i.e. union, intersection and difference of sets, properties of the operations between sets, a general method to prove a set equality, Venn’s diagrams, ordered pairs and Cartesian products.In Chapter 2 we concentrate on the set of real numbers, define rational and irrational numbers, introduce the countable and the uncountable sets concept, show that the set of rational numbers is countable while the set of real numbers is uncountable, and state various other theorems concerning finite and infinite sets.In Chapter 3 we study the powers with positive or negative integer exponents, the radicals, and state some fundamental properties governing the operations with algebraic expressions involving powers and/ or radicals. Finally we show that a power with a fractional exponent is equivalent to a radical, and state all important properties involving powers with fractional exponents.In Chapter 4 we study some (frequently used in Algebra) properties of proportions and state the important Theorem of equal fractions.In Chapter 5 we present a thorough and in depth introduction to the theory of inequalities and state their most common properties. Simple inequalities are solved making use of the related inequality properties.In Chapter 6 we define the absolute value of a real number, state all the fundamental related properties and give some general principles as how to work with problems involving absolute values.In Chapter 7 we present an in depth study of the main algebraic identities, such as the square of the sum or the difference of tw
