Description :


A beautiful part in Maths is inequality. There are a lot of techniques and theorems related to inequality. This is the main reason that inequality problems appear in most Mathematics Competitions. Therefore, if you want to be a part of the competitions, mastering in inequality is one thing that you must do. Challenging Problems in Inequalities is a little book about inequalities. This book will provide you with the basics, techniques and theorems in inequalities. We will guide you through many interesting things in inequalities. This book was written in three main parts. The first part is about techniques and theorems in proving inequalities. The second part is about problems. And the last part of the book is about solutions. In the first part of the book, we try to dive readers into the basic inequalities. We lead readers to understand many well-known theorems such as QM-AM-GM-HM inequality, Cauchy-Schwarz inequality, rearrangement inequality, Jensen's inequality, Schur's inequality and etc. Moreover, in each chapter, we give many examples in order to make to make sure that readers understand well about the theorem. Readers should keep in mind that learning maths is not about memorizing but it is all about understanding. The more you understand about the lesson, the more you perform really well in solving problems. In the second part of the book, we listed many challenging problems from around the world. The aim of this part is to help readers to practice their understanding in the first part. Readers should try their best to solve the given problems before seeing the solutions. It is good to figure the answers out by yourself. However, do not worry if you cannot solve them since the last part of the book is about solutions. In this part, we provide readers very detailed solutions to each problems. All problems were solved step by step. This part will help readers to evolve a lot. We hope this book will help readers a lot in inequalities.

Description :


The connections and interactions of lifelong learning and social justice are complex and contested. Both are seen as a means to unconditional good, with little account taken of the inequalities and equalities located in constructions of power. This book develops critical ways to engage with international debates about lifelong learning and social justice through a range of competing and contested definitions, setting out some of the complexities and challenges of linking the two concepts. In particular, it engages in debates about the equalities and inequalities of learner identities, displacement and place. Its chapters consider those marginalised in complex and multiple ways, including gender, social class, ethnicity, age and migration. This book was originally published as a special issue of the International Journal of Lifelong Education.

Description :


This book is intended for the Mathematical Olympiad students who wish to prepare for the study of inequalities, a topic now of frequent use at various levels of mathematical competitions. In this volume we present both classic inequalities and the more useful inequalities for confronting and solving optimization problems. An important part of this book deals with geometric inequalities and this fact makes a big difference with respect to most of the books that deal with this topic in the mathematical olympiad. The book has been organized in four chapters which have each of them a different character. Chapter 1 is dedicated to present basic inequalities. Most of them are numerical inequalities generally lacking any geometric meaning. However, where it is possible to provide a geometric interpretation, we include it as we go along. We emphasize the importance of some of these inequalities, such as the inequality between the arithmetic mean and the geometric mean, the Cauchy-Schwarz inequality, the rearrangementinequality, the Jensen inequality, the Muirhead theorem, among others. For all these, besides giving the proof, we present several examples that show how to use them in mathematical olympiad problems. We also emphasize how the substitution strategy is used to deduce several inequalities.

This new and expanded edition is intended to help candidates prepare for entrance examinations in mathematics and scientific subjects, including STEP (Sixth Term Examination Paper). STEP is an examination used by Cambridge Colleges for conditional offers in mathematics. They are also used by some other UK universities and many mathematics departments recommend that their applicants practice on the past papers even if they do not take the examination.Advanced Problems in Mathematics bridges the gap between school and university mathematics, and prepares students for an undergraduate mathematics course. The questions analysed in this book are all based on past STEP questions and each question is followed by a comment and a full solution. The comments direct the reader's attention to key points and put the question in its true mathematical context. The solutions point students to the methodology required to address advanced mathematical problems critically and independently.This book is a must read for any student wishing to apply to scientific subjects at university level and for anyone interested in advanced mathematics.

Description :


Nearly a half century after the civil rights movement, racial inequality remains a defining feature of American life. Along a wide range of social and economic dimensions, African Americans consistently lag behind whites. This troubling divide has persisted even as many of the obvious barriers to equality, such as state-sanctioned segregation and overt racial hostility, have markedly declined. How then can we explain the stubborn persistence of racial inequality? In Beyond Discrimination: Racial Inequality in a Post-Racist Era, a diverse group of scholars provides a more precise understanding of when and how racial inequality can occur without its most common antecedents, prejudice and discrimination. Beyond Discrimination focuses on the often hidden political, economic and historical mechanisms that now sustain the black-white divide in America. The first set of chapters examines the historical legacies that have shaped contemporary race relations. Desmond King reviews the civil rights movement to pinpoint why racial inequality became an especially salient issue in American politics. He argues that while the civil rights protests led the federal government to enforce certain political rights, such as the right to vote, addressing racial inequities in housing, education, and income never became a national priority. The volume then considers the impact of racial attitudes in American society and institutions. Phillip Goff outlines promising new collaborations between police departments and social scientists that will improve the measurement of racial bias in policing. The book finally focuses on the structural processes that perpetuate racial inequality. Devin Fergus discusses an obscure set of tax and insurance policies that, without being overtly racially drawn, penalizes residents of minority neighborhoods and imposes an economic handicap on poor blacks and Latinos. Naa Oyo Kwate shows how apparently neutral and apolitical market forces concentrate fast food and alcohol advertising in minority urban neighborhoods to the detriment of the health of the community. As it addresses the most pressing arenas of racial inequality, from education and employment to criminal justice and health, Beyond Discrimination exposes the unequal consequences of the ordinary workings of American society. It offers promising pathways for future research on the growing complexity of race relations in the United States.

Description :


This book offers in-depth analyses of how education interacts with social inequality in Southern contexts. Drawing on a range of disciplinary frameworks, it presents new analyses of existing knowledge and new empirical data which define the challenges and possibilities of successful educational reform. It is a tribute to the work of the late Christopher Colclough, who, as a leading figure in education and international development, played a key role in the global fight for education for all children. The book critically engages with international evidence of educational access, retention and outcomes, offering new understandings of how social inequalities currently facilitate, mediate or restrict educational opportunities. It exposes the continuing influence of wealth and regional inequalities and caste and gendered social structures. Researchers in Ethiopia, Ghana, India, Pakistan and Uganda highlight how the aspirations of families living in poverty remain unfilled by poor-quality education and low economic opportunities and how schools and teachers currently address issues of gender, disability and diversity. The book highlights a range of new priorities for research and identifies some necessary strategies for education reform, policy approaches and school practice, if educational equality for all children is to be achieved. The book will be of great interest to researchers, scholars, educational practitioners and policy-makers in the fields of economics, politics and sociology of education, international education, poverty research and international development.

Innovations and Challenges in Applied Linguistics from the Global South provides an original appraisal of the latest innovations and challenges in applied linguistics from the perspective of the Global South. Global South perspectives are encapsulated in struggles for basic, economic, political and social transformation in an inequitable world, and are not confined to the geographical South. Taking a critical perspective on Southern theories, demonstrating why it is important to view the world from Southern perspectives and why such positions must be open to critical investigation, this book: charts the impacts of these theories on approaches to multilingualism, language learning, language in education, literacy and diversity, language rights and language policy; provides broad historical and geographical understandings of the movement towards a Southern perspective and draws on Indigenous and Southern ways of thinking that challenge mainstream viewpoints; seeks to develop alternative understandings of applied linguistics, expand the intellectual repertoires of the discipline, and challenge the complicities between applied linguistics, colonialism, and capitalism. Written by two renowned scholars in the field, Innovations and Challenges in Applied Linguistics from the Global South is key reading for advanced students and researchers of applied linguistics, multilingualism, language and education, language policy and planning, and language and identity.

More than a decade ago I published some notes on inequalities on the WWW with the same title as this book aimed for mathematical olympiad preparation. I do not have specific data on how widespread it became. However, search results on the WWW, publication data on ResearchGate and occasional emails from teachers and students gave me evidence that it had indeed spread worldwide. While I was greatly overwhelmed and humbled that so many people across the world read my notes and presumably found them useful, I also felt it necessary to write a more detailed and improved version. This culminated in the publication of this book. While the main topics from the original notes have not changed, this book does contain more details and explanations. I therefore hope that it will be even more useful to everyone.
