For courses in Transition to Advanced Mathematics or Introduction to Proof.
Meticulously crafted, student-friendly text that helps build mathematical maturity
Mathematical Proofs: A Transition to Advanced Mathematics, 4th Edition introduces students to proof techniques, analyzing proofs, and writing proofs of their own that are not only mathematically correct but clearly written. Written in a student-friendly manner, it provides a solid introduction to such topics as relations, functions, and cardinalities of sets, as well as optional excursions into fields such as number theory, combinatorics, and calculus. The exercises receive consistent praise from users for their thoughtfulness and creativity. Â They help students progress from understanding and analyzing proofs and techniques to producing well-constructed proofs independently. This book is also an excellent reference for students to use in future courses when writing or reading proofs.
Students learn to construct proofs of their own that are not only mathematically correct but clearly written.
Proof Strategies features precede proofs and encourage students to plan what is needed to present a proof of the result in question.
Proof Analysis features appear after presentations of proofs and discuss key details considered for the creation of the proof.
Communicating Mathematics (Chapter 0) provides a valuable reference for students as the course progresses. This chapter prepares students to write effective and clear exposition by emphasising the correct usage of mathematical symbols, mathematical expressions, and key mathematical terminology.
NEW! A Reviewing Proof Techniques chapter (Chapter 7) has been added to summarise all proof techniques presented to that point. This chapter provides many examples to solidify the understanding of these techniques, emphasising both how and when to use the techniques.
NEW! Presentation slides now accompany every chapter. These presentations provide examples and exposition on key topics. Students and instructors can access the presentations (as PDFs or LaTeX files) via short URLs that appear in the text at the end of each chapter.
Exercises for each section at the end of a chapter (Section Exercises) and additional exercises for the entire chapter (Chapter Supplemental Exercises).
Over 1000 exercises are available.
EXPANDED! More than 100 exercises, examples, and results have been added. Many of the new exercises are in the moderately challenging category.
Difficulty ranges from routine to medium to challenging
True/False exercises present statements and ask students to determine whether they are correct, asking for justification as part of the process.
Proposed proofs of statements ask students if an argument is valid.
Proofs without a statement ask students to supply a statement of what has been proved.
Exercises that call upon students to form conclusions of their own and possibly to provide proofs of these conclusions.
More than 100 exercises, examples, and results have been added, with many of the new exercises created to be moderately challenging.
Presentation slides now accompany every chapter. These presentations provide examples and exposition on key topics. Students and instructors can access the presentations (as PDFs or LaTeX files) via short URLs that appear in the text at the end of each chapter.
Content updates:
Chapter 7, Reviewing Proof Techniques, has been added to summarize all proof techniques presented to that point. This chapter provides many examples to solidify the understanding of these techniques, emphasizing both how and when to use the techniques.
Chapter 13, Proofs in Combinatorics, was added in response to user feedback. The new chapter presents results and examples for this important area of discrete mathematics. Numerous exercises are also included.
Online Chapter 18, Proofs with Real and Complex Numbers, covers these two classes of numbers—with many important classical results on real numbers as well as important results from complex variables. In each case, detailed proofs are given.
