Problems that beset Archimedes, Newton, Euler, Cauchy, Gauss, Monge and other greats, ready to challenge today’s would-be problem solvers. Among them: How is a sundial constructed? How can you calculate the logarithm of a given number without the use of logarithm table? No advanced math is required. 100 problems with proofs.
Contained here are solutions to challenging problems from algebra, geometry, combinatorics and number theory featured in the earlier book, together with selected questions (without solutions) from national and regional Olympiads given during the year 2000. Intended for the serious student/problem solver, these books can help to improve performance in the Mathematical Olympiad competition. However, for those not entering the competition, there is much to challenge any mathematician, even those with advanced degrees. Different nations have different mathematical cultures, so you will find that some of the questions are extremely difficult and some rather easy. There are a wide variety of problems especially from those countries that have often done well in the IMO. Anyone interested in mathematical problem solving will encounter some beautiful mathematics in the pages of this book. If you are up to a real challenge, take some of these problems on!
A brief narrative description of the journal article, document, or resource. This book contains about 200 problems. It is suggested that it be used by students, teachers or anyone interested in exploring mathematics. In addition to a general discussion on problem solving, there are problems concerned with number theory, algebra, geometry, and combinatorics.
ABC Practical Guide to Dog Training is very user-friendly. It focuses on what you, a dog owner, can do starting the very first day you bring your dog home. The book explains what commonly used behavioral terms really mean, explains “pack theory” in a way that makes sense, delves into ways you can humanely and effectively address behavior problems such as jumping, nipping, chewing, house soiling, digging, barking and much more.
Psychopathology in children and adolescents has been extensively researched and addressed in terms of its epidemiology, expression, developmental pathways, and causes. And despite all the research studies and findings, the question remained: Are the emotional and behavioral problems of girls unique to the distinct aspects of female development, behavior, and adjustment? To fully understand and address the emotional and behavioral problems of girls, their distinct characteristics must be examined in terms of both developmental progression and context-that is, in terms of their various ethnic, cultural, socioeconomic backgrounds as well as family, school, and peer environments and influences.
