How to Prove It

Pages : 401

Book Description
Many students have trouble the first time they take a mathematics course in which proofs play a significant role. This new edition of Velleman's successful text will prepare students to make the transition from solving problems to proving theorems by teaching them the techniques needed to read and write proofs. The book begins with the basic concepts of logic and set theory, to familiarize students with the language of mathematics and how it is interpreted. These concepts are used as the basis for a step-by-step breakdown of the most important techniques used in constructing proofs. The author shows how complex proofs are built up from these smaller steps, using detailed 'scratch work' sections to expose the machinery of proofs about the natural numbers, relations, functions, and infinite sets. To give students the opportunity to construct their own proofs, this new edition contains over 200 new exercises, selected solutions, and an introduction to Proof Designer software. No background beyond standard high school mathematics is assumed. This book will be useful to anyone interested in logic and proofs: computer scientists, philosophers, linguists, and of course mathematicians.

Book Description
Inspire performance and prove your leadership impact Prove It! is the executive guide to improving organisational performance through the practice of evidence-based leadership. More than ever before, the world is demanding transparency and accountability from organisational leaders, and there is a growing push to hold leaders responsible for the performance of their organisation. Many executives panic at the thought of what transparency might reveal and how they might be held accountable, but others relish the opportunity to showcase their organisation's performance. The difference is in the leadership methodology. The best leaders already know how their organisation is performing, and that it has improved during their tenure – and they can prove it because they practise evidence-based leadership. This book offers a clear blueprint for building on your existing skills and performance management systems to build a truly high performance organisation. Just three personal leadership habits and three organisation-wide habits can transform your organisation into the powerhouse you know it can be. With a simple methodology and a focus on practical results, this book can help you: Set a strategic direction that really does inspire organisational excellence Gain a true picture of your organisation's performance Master the habits that help you lead a high-performance culture Improve your organisation objectively, measurably and quickly If an organisation can only be as good as its leadership, it's reasonable to place the burden of performance responsibility on those who make the decisions. A leader's job is to inspire, motivate and guide, and those who do it well are already raising the bar. Prove It! gives you a practical model for measurable, real-world results, starting today.

Category : Mathematics
Languages : en
Pages : 194

Book Description
According to the great mathematician Paul Erdös, God maintains perfect mathematical proofs in The Book. This book presents the authors candidates for such "perfect proofs," those which contain brilliant ideas, clever connections, and wonderful observations, bringing new insight and surprising perspectives to problems from number theory, geometry, analysis, combinatorics, and graph theory. As a result, this book will be fun reading for anyone with an interest in mathematics.

100% Mathematical Proof

Pages : 332

Book Description
"Proof" has been and remains one of the concepts which characterises mathematics. Covering basic propositional and predicate logic as well as discussing axiom systems and formal proofs, the book seeks to explain what mathematicians understand by proofs and how they are communicated. The authors explore the principle techniques of direct and indirect proof including induction, existence and uniqueness proofs, proof by contradiction, constructive and non-constructive proofs, etc. Many examples from analysis and modern algebra are included. The exceptionally clear style and presentation ensures that the book will be useful and enjoyable to those studying and interested in the notion of mathematical "proof."

Book Description
What do you say when someone tries to tell you: "You're not a Christian because your church isn't Bible-based?" "You're not a Christian because what your church teaches isn't in the Bible?" "You're not a Christian because you believe that good works will get you to heaven?" "You're not a Christian because you worship Mary like a goddess?" "You're not a Christian because you believe that the pope is right about everything?" "You're not a Christian because you obey the pope instead of God?" And the biggie: "You're not a Christian because you're not saved?" Prove It! Church gives you the answers you need when someone challenges your Catholic Faith. From Mary to the saints to papal infallibility, infant baptism, purgatory, and a whole lot more. Prove It! Church explains what you need to know to prove that the Catholic Church belongs to Christ, teaches Christ, preaches Christ - and is, in fact, Christ in the world today!

Why Prove it Again?

Author: John W. Dawson, Jr.
Publisher: Birkhäuser
ISBN: 3319173685
Category : Mathematics
Languages : en
Pages : 211

Book Description
This monograph considers several well-known mathematical theorems and asks the question, “Why prove it again?” while examining alternative proofs. It explores the different rationales mathematicians may have for pursuing and presenting new proofs of previously established results, as well as how they judge whether two proofs of a given result are different. While a number of books have examined alternative proofs of individual theorems, this is the first that presents comparative case studies of other methods for a variety of different theorems. The author begins by laying out the criteria for distinguishing among proofs and enumerates reasons why new proofs have, for so long, played a prominent role in mathematical practice. He then outlines various purposes that alternative proofs may serve. Each chapter that follows provides a detailed case study of alternative proofs for particular theorems, including the Pythagorean Theorem, the Fundamental Theorem of Arithmetic, Desargues’ Theorem, the Prime Number Theorem, and the proof of the irreducibility of cyclotomic polynomials. Why Prove It Again? will appeal to a broad range of readers, including historians and philosophers of mathematics, students, and practicing mathematicians. Additionally, teachers will find it to be a useful source of alternative methods of presenting material to their students.

O.J. Is Innocent and I Can Prove It

Author: William C. Dear
Publisher: Skyhorse

Category : True Crime
Languages : en
Pages : 392

Book Description
Nicole Brown Simpson and Ron Goldman were brutally murdered at her home on Bundy Drive in Brentwood, California, on the night of June 12, 1994. The days and weeks that followed were full of spectacle, including a much-watched car chase and the eventual arrest of O. J. Simpson for the murders. The televised trial that followed was unlike any that the nation had ever seen. Long since convinced of O. J.’s guilt, the world was shocked when the jury of the “trial of the century” read the verdict of not guilty. To this day, the LAPD, Los Angeles District Attorney’s office, mainstream media, and much of the world at large remain firmly convinced that O. J. Simpson got away with murder. According to private investigator William Dear, it is precisely this assuredness that has led both the police and public to overlook a far more likely suspect. Dear now compiles more than seventeen years of investigation by his team of forensic experts and presents evidence that O. J. was not the killer. In O. J. Is Innocent and I Can Prove It, Dear makes the controversial, but compelling, case that it may have been the “overlooked suspect,” O. J.’s eldest son, Jason, who committed the grisly murders. Sure to stir the pot and raise some eyebrows, this book is a must-read.
