. . Algebra's importance lies in the student's future. . . as essential preparation for the serious study of science, engineering, economics, or for more advanced types of mathematics. . . The primary importance of trigonometry is not in its applications to surveying and navigation, or in making computations about triangles, but rather in the mathematical description of vibrations, rotations, and periodic phenomena of all kinds, including light, sound, alternating currents, and the orbits of the planets around the sun. In this brief, clearly written book, the essentials of geometry, algebra, and trigonometry are pulled together into three complementary and convenient small packages, providing an excellent preview and review for anyone who wishes to prepare to master calculus with a minimum of misunderstanding and wasted time and effort. Students and other readers will find here all they need to pull them through.

    

    Over the centuries, cities and governments have risen and fallen beyond the concent's walls. Three times during history's darkest epochs violence born of superstition and ignorance has invaded and devastated the cloistered mathic community. Yet the avout have always managed to adapt in the wake of catastrophe, becoming out of necessity even more austere and less dependent on technology and material things. And Erasmas has no fear of the outside—the Extramuros—for the last of the terrible times was long, long ago.Now, in celebration of the week-long, once-in-a-decade rite of Apert, the fraas and suurs prepare to venture beyond the concent's gates—at the same time opening them wide to welcome the curious "extras" in. During his first Apert as a fraa, Erasmas eagerly anticipates reconnecting with the landmarks and family he hasn't seen since he was "collected." But before the week is out, both the existence he abandoned and the one he embraced will stand poised on the brink of cataclysmic change.Powerful unforeseen forces jeopardize the peaceful stability of mathic life and the established ennui of the Extramuros—a threat that only an unsteady alliance of saecular and avout can oppose—as, one by one, Erasmas and his colleagues, teachers, and friends are summoned forth from the safety of the concent in hopes of warding off global disaster. Suddenly burdened with a staggering responsibility, Erasmas finds himself a major player in a drama that will determine the future of his world—as he sets out on an extraordinary odyssey that will carry him to the most dangerous, inhospitable corners of the planet . . . and beyond.

    Each chapter includes many illustrative examples to assist the reader. The book emphasizes methods for finding solutions to differential equations. It provides many abundant exercises, applications, and solved examples with careful attention given to readability. Elementary Differential Equations includes a thorough treatment of power series techniques. In addition, the book presents a classical treatment of several physical problems to show how Fourier series become involved in the solution of those problems. The eighth edition of Elementary Differential Equations has been revised to include a new supplement in many chapters that provides suggestions and exercises for using a computer to assist in the understanding of the material in the chapter. It also now provides an introduction to the phase plane and to different types of phase portraits. A valuable reference book for readers interested in exploring the technological and other applications of differential equations.

    In the jungles of Malaysia, a mysterious buyer purchases deadly cavitation technology, built to his specifications.

Gripping and thought-provoking, State of Fear is Michael Crichton at his very best.

    Curt Wilcox knew old cars, and he knew immediately that this one was...wrong, just wrong.

    Wade have on violent crime? Freakonomics will literally redefine the way we view the modern world.These may not sound like typical questions for an economist to ask. But Steven D. Levitt is not a typical economist. He is a much heralded scholar who studies the stuff and riddles of everyday life -- from cheating and crime to sports and child rearing -- and whose conclusions regularly turn the conventional wisdom on its head. He usually begins with a mountain of data and a simple, unasked question. Some of these questions concern life-and-death issues; others have an admittedly freakish quality. Thus the new field of study contained in this book: freakonomics.Through forceful storytelling and wry insight, Levitt and co-author Stephen J. Dubner show that economics is, at root, the study of incentives -- how people get what they want, or need, especially when other people want or need the same thing. In Freakonomics, they set out to explore the hidden side of ... well, everything. The inner workings of a crack gang. The truth about real-estate agents. The myths of campaign finance. The telltale marks of a cheating schoolteacher. The secrets of the Ku Klux Klan.What unites all these stories is a belief that the modern world, despite a surfeit of obfuscation, complication, and downright deceit, is not impenetrable, is not unknowable, and -- if the right questions are asked -- is even more intriguing than we think. All it takes is a new way of looking. Steven Levitt, through devilishly clever and clear-eyed thinking, shows how to see through all the clutter.Freakonomics establishes this unconventional premise: If morality represents how we would like the world to work, then economics represents how it actually does work. It is true that readers of this book will be armed with enough riddles and stories to last a thousand cocktail parties. But Freakonomics can provide more than that. It will literally redefine the way we view the modern world.(front flap)

    Seconded to a Home Office Statistical Unit, for what he considers a minor violation of trust, Detective Constable John Gallagher is not well pleased. He knows nothing of statistics but the summer of 1966 reveals he doesn't have to.

    This work tells the story of this one-off guitarist who came to prominence through the debauchery and stellar chart success of the American west coast's Guns N' Roses. Full description

    It's not a place for a frizzy-haired science nerd, particularly when her fashion-obsessed older sister Sloane is the head of a clique of pretty girls who rule the school -- and practically the whole town. Fortunately, life is about to change forever. Lucy's dad is getting re-married, and then she can transfer to a boarding school in Connecticut, escaping all the mean girls and the endless whispers about the Whitley family scandal.

    Little did he know when he opened his club under a flophouse on the Bowery that it would become the birthplace of a new era of music in New York City - Punk. While the letters CBGB ultimately didn't describe the music the club was renowned for, OMFUG (Other Music for Uplifting Gourmandizers) still represents what the club provides for all voracious consumers of music. These pages pay homage to a musical and cultural landmark. It is a spectacular photography compilation which features some of the most celebrated artists in musical history and chronicles the last 30 years of rock and roll. It also showcases photographs of famous patrons, including Andy Warhol, Allen Ginsberg and Jim Jarmusch.

    He's covered extreme metal, extreme nostalgia, disposable art, disposable heroes, life on the road, life through the television, urban uncertainty and small-town weirdness. Through a variety of mediums and with a multitude of motives, he's written about everything he can think of (and a lot that he's forgotten). The world keeps accelerating, but the pop ideas keep coming.In Eating the Dinosaur, Klosterman is more entertaining and incisive than ever. Whether he's dissecting the boredom of voyeurism, the reason why music fans inevitably hate their favorite band's latest album, or why we love watching can't-miss superstars fail spectacularly, Klosterman remains obsessed with the relationship between expectation, reality, and living history. It's amateur anthropology for the present tense, and sometimes it's incredibly funny.

    Professor Lofti Zadeh masterminded "fuzzy logic"--a way of programming computers to "make decisions" bases on imprecise data and complex situations.

How Would You Move Mount Fuji? is an indispensable book for anyone in business. Managers seeking the most talented employees will learn to incorporate puzzle interviews in their search for the top candidates. Job seekers will discover how to tackle even the most brain-busting questions, and gain the advantage that could win the job of a lifetime.
