Charming Proofs

The DOLCIANI MATHEMATICAL EXPOSITIONS series of the Mathematical Association of America was established through a generous gift to the Association from Mary P. Dolciani, Professor of Mathematics at Hunter College of the City University of New York. In making the gift, Professor Dolciani, herself an exceptionally talented and successful expositor of mathematics, had the purpose of furthering the ideal of excellence in mathematical exposition. The Association, for its part, was delighted to accept the gracious gesture initiating the revolving fund for this series from one who has served the Association with distinction, both as a member of the Committee on Publications and as a member of the Board of Governors. It was with genuine pleasure that the Board chose to name the series in her honor.

DISCRETE-TIME SIGNAL PROCESSING

This third edition of Discrete-Time Signal Processing is a descendent of our original textbook Digital Signal Processing published in 1975. That very successful text appeared at a time when the field was young and just beginning to develop rapidly. At that time the topic was taught only at the graduate level and at only a very few schools. Our 1975 text was designed for such courses. It is still in print and is still used successfully at a number of schools in the United States and internationally. By the 1980's, the pace of signal processing research, applications and implementation technology made it clear that digital signal processing (DSP) would realize and exceed the potential that had been evident in the 1970's. The burgeoning importance of DSP clearly justified a revision and updating of the original text. In organizing that revision, it was clear that so many changes had occurred both in the field and in the level and style with which the topic was taught, that it was most appropriate to develop a new textbook, strongly based on our original text, while keeping the original text in print. We titled the new book, published in 1989, Discrete-Time Signal Processing to emphasize that most of the DSP theory and design techniques discussed in the text apply to discrete-time systems in general, whether analog or digital.

Convex Analysis and Optimization

This book focuses on the theory of convex sets and functions, and its connections with a number of topics that span a broad range from continuous to discrete optimization. These topics include Lagrange multiplier theory, Lagrangian and conjugate/Fenchel duality, minimax theory, and nondifferentiable optimization. The book evolved from a set of lecture notes for a graduate course at M.I.T. It is widely recognized that, aside from being an eminently useful subject in engineering, operations research, and economics, convexity is an excellent vehicle for assimilating some of the basic concepts of real analysis within an intuitive geometrical setting. Unfortunately, the subject's coverage in academic curricula is scant and incidental. We believe that at least part of the reason is the shortage of textbooks that are suitable for classroom instruction, particularly for nonmathematics majors. We have therefore tried to make convex analysis accessible to a broader audience by emphasizing its geometrical character, while maintaining mathematical rigor. We have included as many insightful illustrations as possible, and we have used geometric visualization as a principal tool for maintaining the students' interest in mathematical proofs.

PEMBINAAN OLIMPIADE MATEMATIKA

Alhamdulillah Penulis ucapkan kepada Allah, SWT karena dengan karunia-Nya Penulis dapat menyelesaikan penulisan diktat ini. Diktat ini Penulis tulis dalam rangka mempermudah tugas dalam mempersiapkan siswa-siswa SMA menghadapi olimpiade matematika pada tahap-tahap awal. Menurut pengamatan Penulis, masih ada jurang pemisah yang cukup jauh antara siswasiswa dari pulau Jawa dengan dari luar pulau Jawa. Masih sangat banyak siswa-siswa di luar pulau Jawa yang belum memahami persoalan-persoalan dasar di bidang Olimpiade Matematika sehingga mengalami kesulitan besar ketika akan menghadapi OSN. Buku ini berusaha menjawab tentang persoalan-persoalan mendasar di bidang Olimpiade Matematika tersebut. Para guru pembina olimpiade diharapkan dalam membina siswa-siswa juga memberikan soal-soal pada tingkatan OSN pada kegiatan umpan balik yang dapat dilaksanakan setelah guru menyelesaikan pembinaan pada setiap babnya.

DIFFERENTIAL GEOMETRY OF CURVES & SURFACES

In this edition, I have included many of the corrections and suggestions kindly sent to me by those who have used the book. For several reasons it is impossible to mention the names of all the people who generously donated their time doing that. Here I would like to express my deep appreciation and thank them all. Thanks are also due to John Grafton, Senior Acquisitions Editor at Dover Publications, who believed that the book was still valuable and included in the text all of the changes I had in mind, and to the editor, James Miller, for his patience with my frequent requests. As usual, my wife, Leny A. Cavalcante, participated in the project as if it was a work of her own; and I might say that without her this volume would not exist. Finally, I would like to thank my son, Manfredo Jr., for helping me with several figures in this edition.

DIFFERENTIAL CALCULUS

This book is meant for students preparing for the B.A. and B.Sc. examinations of our universities. Some topics of the Honours standard have also been included. They are given in the form of appendices to the relevant chapters. The treatment of the subject is rigorous but no attempt has been made to state and prove the theorems in generalised forms and under less restrictive conditions as is the case with the Modern Theory of Function. It has also been a constant endeavour of the author to see that the subject is not presented just as a body of formulae. This is to see that the student does not form an unfortunate impression that the study of Calculus consists only in acquiring a skill to manipulate some formulae through 'constant drilling'.

Data Structures and Algorithms with JavaScript

Over the past few years, JavaScript has been used more and more as a server-side computer programming language owing to platforms such as Node.js and SpiderMonkey. Now that JavaScript programming is moving out of the browser, programmers will find they need to use many of the tools provided by more conventional languages, such as C++ and Java. Among these tools are classic data structures such as linked lists, stacks, queues, and graphs, as well as classic algorithms for sorting and searching data. This book discusses how to implement these data structures and algorithms for server-side JavaScript programming. JavaScript programmers will find this book useful because it discusses how to implement data structures and algorithms within the constraints that JavaScript places them, such as arrays that are really objects, overly global variables, and a prototype-based object system. JavaScript has an unfair reputation as a “bad” programming language, but this book demonstrates how you can use JavaScript to develop efficient and effective data structures and algorithms using the language’s “good parts.”
