Publishing Date: 2004-01-01
Features: As requested by the publisher, we have revised some content of "Early Morning Bus for Mathematical Olympiad - Daily Training" and "Express Bus for Mathematical Olympiad - Pre-Competition Training." Two years ago, when this series of books was published, I wrote a preface sharing some thoughts and the origin of these books. Now, I'd like to take this revision opportunity to say something off-topic. This year, there is a major mathematics-related event—the 2002 International Congress of Mathematicians will be held in Beijing in August. This is not only an "Olympiad" for mathematicians but also a rare opportunity to promote and publicize mathematics. Never before have so many media outlets reported on the current state of mathematical development, introduced mathematicians, and discussed the relationship between mathematics and public life. To coincide with the mathematicians' congress, relevant organizations have also organized the "Exploring the Wonderful Garden of Mathematics" China Youth Mathematics Forum for primary and secondary school students, allowing them to have close contact with mathematical masters and listen to the teachings of mathematicians. The content of this book includes the third part: Fun Park, Special Topic Training, and Key Insights. The detailed content includes Popular programs such as "Dividing the Cake," "Money Exchange Machine," "Quartering a Circle," "Using Congruence Only," "Four Cats," "Three Guards and a Leopard," "Area of the Track," "Dividing Mooncakes," "Who Is the Drummer? Cleverly Surrounding the Forest," "Postal Stamp Calculation," "Dominoes," "City Within a City," "17 Scientists," "Sunspots," "The Duke's Wish," "Do More Exercises," "Going to the Movies," "The Cockroach Seeking Truth," "The Death of Ghana," and "Airplane Landing"; the second part includes special topic training, the relationship between roots and systems, discriminants, equations and systems of equations, indeterminate equations, inequalities, properties and applications of circles, problems involving circles, circle and proportionality, Gaussian functions, functions and their expressions, comprehensive exercises (I), function graphs, the value (I) of functions, the value (II) of functions, the pigeonhole principle, chessboard coloring, polynomials, geometric inequalities, solving triangles, important theorems in geometry, etc.
