Both authors richly deserve their reputations as problem selectors of great taste and discernment. There is a large list of exercises with solutions, some taken from Mathematical Olympiad competitions.

Thus the book is also a valuable resource for teachers and those interested in mathematical competitions. The first half of the book presents the complex numbers and their geometric properties in depth. The second half is a collection of exercises with solutions. Much of the book goes to geometric applications, of course, but there are also sections on polynomial equations, trigonometry, combinatorics Problems constitute an integral part of the book alongside theorems, lemmas and examples.

The problems are embedded in the text throughout the book, partly as illustrations to the discussed concepts, partly as the testing grounds for the techniques just studied, but mostly I believe to emphasize the centrality of problem solving in the authors’ world view The book is really about solving problems and developing tools that exploit properties of complex numbers The ttiu will find a good deal of elegant and simple sample problems and even a greater quantity of technically taxing ones.

The book supplies ritu great tools to help solve those problems. As the techniques go, the book is truly From ‘A to Z’. It is for somebody who made it their business to be solving problems on a regular basis.

These readers will appreciate the scope of the methodological detail the authors of the book bring to their attention, they will appreciate the power of the methods and theintricacy of the problems. The theory appears strictly connected with the problems, the hardest world contest included.

Both of them have a very rich experience in preparing Olympic teams in Romania and in the United States. I strongly recommend the book for pupils, students and teachers. It is impossible to imagine modern mathematics without complex numbers. Euler, has become one of the domplex utilized ideas in mathematics. The exposition concentrates on key concepts and then elementary results concerning these numbers. The reader learns how complex numbers can be used to solve algebraic equations and to understand the geometric interpretation of complex numbers and the operations involving them.

The theoretical parts of the book are andreezcu with rich exercises and problems at various levels of difficulty.

### Complex Numbers from A to Z : Titu Andreescu :

Many new problems and solutions have been added in this second edition. A special feature of the book is the last chapter, a selection of outstanding Olympiad and other important mathematical contest problems solved by employing the methods already presented.

The book reflects the unique experience of the authors. It distills a vast mathematical literature, most of which is unknown to the western public, and captures the essence of an abundant problem culture. The target audience includes undergraduates, high school students and their teachers, mathematical contestants such as those training for Olympiads or the W.

Putnam Mathematical Competition and their coaches, as well as anyone interested in essential mathematics.

When I first started reading the book it looked like a typical math book with the kind of math proofs that I hated in high school and college. But I soon warmed up to the book and am learning all kinds of great things about complex numbers.

Some of the proofs and exercises are beyond me but most is just clever algebra. I highly recommend this book. Good book, especially for introductory complex geometry. The theory of complex numbers is built up in black and white, no frills i.

The mathematical exposition is generally concise, clear and rigorous. The only problem with the book is the occasional error. But the only errors I have found are minor in the sense that 1 There are very few of them and 2 They are numeric The process is correct but the answer numbeers wrong because of titj simple arithmetic mistake. Fast delivery andreescj thanks. The book is a must for any complex numbers enthusiast.

Actually I didn’t buy this book but just download it from Andrwescu library’s website. I mean, it’s Stanford’s website, right? But I have to thank the author for writing such a great book.

I didn’t learn much about complex numbers in my high school, and don’t feel comfortable with my college complex analysis textbook, so I got this book to build a firm foundation for my complex analysis class. As a Math major, I really love the way this book is written. Anyway, I would recommend this book to anyone who wants to take complex analysis because a lot of us don’t have enough knowledge about complex numbers but the complex analysis class is based on the assumption that we are already masters of it.

Mathematics is amazing not only in its power and beauty, but also in the way that it has applications in so many areas.

## Complex Numbers from A to …Z

The aim of this book is to stimulate young people to become interested in mathematics, to enthuse, inspire, and challenge them, their parents and their teachers with the wonder, excitement, power, and relevance of mathematics. This book is a very well written introduction to the fascinating theory of complex numbers and it contains a fine collection of excellent exercises ranging in difficulty from the fairly easy, if calculational, to the more challenging.

As stated by the authors, the targeted audience is not standard and it “includes high school students and their teachers, undergraduates, mathematics contestants such as those training for Olympiads or the William Lowell Putnam Mathematical Competition, their coaches, and any person interested in essential mathematics.

An important feature of this marvelous book is that it presents a wide range of problems of all degrees of difficulties, but also that it includes easy proofs and natural generalizations of many theorems in elementary geometry. The authors show how to approach the solution of such problems, emphasizing the use of methods rather than the mere use of formulas. Of course, the more sophisticated the problems become, the more specific this approach has to be chosen. The book is self-contained; no background in complex numbers is assumed and complete solutions to routine problems and to olympiad-caliber problems are presented in the last chapter of the book.

The aim of the core part of each chapter is to develop key mathematical ideas and to place them in the context of novel, interesting, and unexpected applications to real-world problems. The first chapter deals with complex numbers in algebraic form and leads up to the geometric interpretations of the modulus and of the algebraic operations. Chapter 3 is devoted to the applications of complex numbers in solving problems in Plane and Analytic Geometry.

This chapter includes a lot of interesting properties related to collinearity, orthogonality, concyclicity, similar triangles, as well as very useful analytic formulas for the geometry of a triangle and of a circle in the complex plane.

Chapter 4 contains much more powerful results such as: This chapter also includes a marvelous theorem known in the mathematical folklore under the name of “Morley’s Miracle” and which simply states that “the three points of intersection of the adjacent trisectors of any triangle form an equilateral triangle”. As stated in the book, this theorem was mistakenly attributed to Napoleon Bonaparte.

The proof of this theorem follows directly from Theorem 3 on pagea deep result which was obtained by the celebrated French mathematician Alain Connes Fields Medal in and Clay Research Award inin connection with his revolutionary results in Noncommutative Geometry. Chapter 5 illustrates the force of the method of complex numbers in solving several Olympiad-caliber problems where this technique works very efficiently.

## Complex Numbers from A to … Z

This comppex successful book is the fruit of the prodigious activity of two well-known creators of mathematics problems in various mathematical journals. The big experience of the authors in preparing students for various mathematical competitions allowed them to present a big collection of beautiful problems. This book continues the tradition making national and international mathematical competition problems available to a wider audience and is bound to appeal to anyone interested in mathematical numberss solving.

I very strongly recommend nmbers book to all students curious about elementary mathematics, especially those who are bored at school and ready for a challenge. Teachers would find this book to be a welcome resource, as will contest organizers. This book is meant andrwescu to be read and to be used. All in all, an excellent book for its intended audience! Goes over the basics of complex numbers from A to Z and is absolutely loaded with examples and practice problems.

I wish it was more proofs and less practice problems, but that’s just a personal preference. Comprehensive and yet concise enough to cover lots of material. Lots of wonderful questions to challenge any math problem lovers. This is a complete work about complex numbers. Perfect for Mathematical Olympiads. A lot of difficult problems. See all 8 reviews.
