Limits, Series, and Fractional Part Integrals


Book Description

This book features challenging problems of classical analysis that invite the reader to explore a host of strategies and tools used for solving problems of modern topics in real analysis. This volume offers an unusual collection of problems — many of them original — specializing in three topics of mathematical analysis: limits, series, and fractional part integrals. The work is divided into three parts, each containing a chapter dealing with a particular problem type as well as a very short section of hints to select problems. The first chapter collects problems on limits of special sequences and Riemann integrals; the second chapter focuses on the calculation of fractional part integrals with a special section called ‘Quickies’ which contains problems that have had unexpected succinct solutions. The final chapter offers the reader an assortment of problems with a flavor towards the computational aspects of infinite series and special products, many of which are new to the literature. Each chapter contains a section of difficult problems which are motivated by other problems in the book. These ‘Open Problems’ may be considered research projects for students who are studying advanced calculus, and which are intended to stimulate creativity and the discovery of new and original methods for proving known results and establishing new ones. This stimulating collection of problems is intended for undergraduate students with a strong background in analysis; graduate students in mathematics, physics, and engineering; researchers; and anyone who works on topics at the crossroad between pure and applied mathematics. Moreover, the level of problems is appropriate for students involved in the Putnam competition and other high level mathematical contests.




(Almost) Impossible Integrals, Sums, and Series


Book Description

This book contains a multitude of challenging problems and solutions that are not commonly found in classical textbooks. One goal of the book is to present these fascinating mathematical problems in a new and engaging way and illustrate the connections between integrals, sums, and series, many of which involve zeta functions, harmonic series, polylogarithms, and various other special functions and constants. Throughout the book, the reader will find both classical and new problems, with numerous original problems and solutions coming from the personal research of the author. Where classical problems are concerned, such as those given in Olympiads or proposed by famous mathematicians like Ramanujan, the author has come up with new, surprising or unconventional ways of obtaining the desired results. The book begins with a lively foreword by renowned author Paul Nahin and is accessible to those with a good knowledge of calculus from undergraduate students to researchers, and will appeal to all mathematical puzzlers who love a good integral or series.




Limits, Series, and Fractional Part Integrals


Book Description

In mathematics, a limits in the value that a function or sequence approaches as the input or index approaches some value. Limits are essential to calculus (and mathematical analysis in general) and are used to define continuity, derivatives, and integrals. Many times, a function can be undefined at a point, but we can think about what the function approaches as it gets closer and closer to that point (this in the limit). Other times, the function may be defined at a point, but it may approach a different limit. There are many times where the function value in the same as the limit at the point. Either way, this is a powerful tool as we start thinking about slope of a tangent line to curve. We often attempt to find the limit at a point where the function itself in not defined. In mathematic, a series is, informally speaking, the sun of the terms if an infinite sequence. The sum of a finite sequence has defined first and last terms, whereas a series continues indefinitely. The terms of the series are often produced according to a rule, such as by a formula, or by an algorithm. Fore emphasizing that there are an infinite numbers of terms, a series is often called an infinite series. The study on infinite series is a major part of mathematical analysis. Series are used in most areas of mathematical, even for studying finite structures, through generating function. The fractional part of a non-negative real number x is the excess beyond that numbers integer part. This book offers an unusual collection of problemmany of them original specializing in three topics on mathematical analysis; limits, series, and fractional part integrals. This book should be of immense valuable for undergraduate students with a strong background in analysis; graduate students in mathematical, physics, and engineering; and anyone who works on topic at the crossroad between pure and applied mathematics.




Sharpening Mathematical Analysis Skills


Book Description

This book gathers together a novel collection of problems in mathematical analysis that are challenging and worth studying. They cover most of the classical topics of a course in mathematical analysis, and include challenges presented with an increasing level of difficulty. Problems are designed to encourage creativity, and some of them were especially crafted to lead to open problems which might be of interest for students seeking motivation to get a start in research. The sets of problems are comprised in Part I. The exercises are arranged on topics, many of them being preceded by supporting theory. Content starts with limits, series of real numbers and power series, extending to derivatives and their applications, partial derivatives and implicit functions. Difficult problems have been structured in parts, helping the reader to find a solution. Challenges and open problems are scattered throughout the text, being an invitation to discover new original methods for proving known results and establishing new ones. The final two chapters offer ambitious readers splendid problems and two new proofs of a famous quadratic series involving harmonic numbers. In Part II, the reader will find solutions to the proposed exercises. Undergraduate students in mathematics, physics and engineering, seeking to strengthen their skills in analysis, will most benefit from this work, along with instructors involved in math contests, individuals who want to enrich and test their knowledge in analysis, and anyone willing to explore the standard topics of mathematical analysis in ways that aren’t commonly seen in regular textbooks.
