101 Problems in Algebra From the Training of the USA IMO Team (Enrichment Series, Volume 18)

Titu Andreescu, Bogdan Enescu

"Mathematical Olympiad Treasures" aims at building a bridge between ordinary high school examples and exercises and more sophisticated, intricate and abstract concepts and problems in undergraduate mathematics. The book contains a stimulating collection of problems in the subjects of geometry and trigonometry, algebra, number theory and combinatorics. While it may be considered a sequel to "Mathematical Olympiad Challenges," the focus of "Treasures" is on engaging a wider audience of undergraduates to think creatively in applying techniques and strategies to problems in the real world. The problems are clustered by topic into self-contained sections. Unlike "Challenges," however, "Treasures" begins with elementary facts, followed by a number of carefully selected problems and an extensive discussion of their solutions. This discussion then leads to more complicated and more intellectually challenging problems as well as their solutions. Throughout the book students are encouraged to express their ideas, conjectures, and conclusions in writing. The goal is to help readers develop a host of new mathematical tools and strategies that will be useful beyond the classroom and in a number of disciplines. "Mathematical Olympiad Treasures" reflects the experience of two experienced professors and coaches from the United States and Romanian Olympiad teams. Leer más…

Questions Of Maxima And Minima Have Great Practical Significance, With Applications To Physics, Engineering, And Economics; They Have Also Given Rise To Theoretical Advances, Notably In Calculus And Optimization. Indeed, While Most Texts View The Study Of Extrema Within The Context Of Calculus, This Carefully Constructed Problem Book Takes A Uniquely Intuitive Approach To The Subject: It Presents Hundreds Of Extreme-value Problems, Examples, And Solutions Primarily Through Euclidean Geometry. Key Features And Topics: * Comprehensive Selection Of Problems, Including Greek Geometry And Optics, Newtonian Mechanics, Isoperimetric Problems, And Recently Solved Problems Such As Malfatti’s Problem * Unified Approach To The Subject, With Emphasis On Geometric, Algebraic, Analytic, And Combinatorial Reasoning * Presentation And Application Of Classical Inequalities, Including Cauchy--schwarz And Minkowski’s Inequality; Basic Results In Calculus, Such As The Intermediate Value Theorem; And Emphasis On Simple But Useful Geometric Concepts, Including Transformations, Convexity, And Symmetry * Clear Solutions To The Problems, Often Accompanied By Figures * Hundreds Of Exercises Of Varying Difficulty, From Straightforward To Olympiad-caliber Written By A Team Of Established Mathematicians And Professors, This Work Draws On The Authors’ Experience In The Classroom And As Olympiad Coaches. By Exposing Readers To A Wealth Of Creative Problem-solving Approaches, The Text Communicates Not... Leer más…

Edited By Titu Andreescu And Zuming Feng

This volume contains a large range of problems, with and without solutions, taken from 25 national and regional mathematics olympiads from around the world, and the problems are drawn from several years' contests. In many cases, more than one solution is given to a single problem in order to highlight different problem-solving strategies. The collection is intended as practice for students preparing for these competitions. Teachers and general readers looking for interesting problems will find also it very useful. Leer más…

Contained here are solutions to challenging problems from algebra, geometry, combinatorics and number theory featured in the earlier book, together with selected questions (without solutions) from national and regional Olympiads given during the year 2000. Intended for the serious student/problem solver, these books can help to improve performance in the Mathematical Olympiad competition. However, for those not entering the competition, there is much to challenge any mathematician, even those with advanced degrees. Different nations have different mathematical cultures, so you will find that some of the questions are extremely difficult and some rather easy. There are a wide variety of problems especially from those countries that have often done well in the IMO. Anyone interested in mathematical problem solving will encounter some beautiful mathematics in the pages of this book. If you are up to a real challenge, take some of these problems on! Leer más…

The Mathematical Olympiad examinations, covering the USA Mathematical Olympiad (USAMO) and the International Mathematical Olympiad (IMO), have been published annually since 1976 by the MAA American Mathematics Competitions. This is the fourth volume in that series published by the MAA in its Problem Book series. The IMO is a world mathematics competition for high school students that takes place each year in a different country. Students from all over the world participate in this competition. The USAMO and the Team Selection Test are the last two stages of the process that lead to the selection of the team representing the USA in the IMO. Problems and solutions from both of these competitions for the year 2003 are included in this volume. These Olympiad style exams consist of several challenging essay-type problems. Although a correct and complete solution to an Olympiad problem often requires deep analysis and careful argument, the problems require no more than a solid background in high school mathematics coupled with a dose of mathematical ingenuity. There are helpful hints provided for each of the problems. These hints often help lead the student to a solution of the problem. Complete solutions to each of the problems is also included, and many of the problems are presented together with a collection of remarkable solutions developed by the examination committees, contestants and experts, during or after the contest. For each problem with... Leer más…

The International Mathematical Olympiad (IMO) is an annual international mathematics competition held for pre-collegiate students. It is also the oldest of the international science olympiads, and competition for places is particularly fierce. This book is an amalgamation of the first 8 of 15 booklets originally produced to guide students intending to contend for placement on their country's IMO team. The material contained in this book provides an introduction to the main mathematical topics covered in the IMO, which are: Combinatorics, Geometry and Number Theory. In addition, there is a special emphasis on how to approach unseen questions in Mathematics, and model the writing of proofs. Full answers are given to all questions. Though A First Step to Mathematical Olympiad Problems is written from the perspective of a mathematician, it is written in a way that makes it easily comprehensible to adolescents. This book is also a must-read for coaches and instructors of mathematical competitions. Leer más…

This book is a compilation of many suggestions, much advice, and even more hard work. Its main objective is to provide solutions to the problems which were originally proposed in the first 12 chapters of "Problems from the Book". The volume is far more than a collection of solutions. The solutions are used as motivation for the introduction of some very clear expositions of mathematics. And this is modern, current, up-to-the-minute mathematics. This is absolutely state-of-the-art material. Everyone who loves mathematics and mathematical thinking should acquire this book. Straight from the boook Leer más…
