特别提示:“集合”语言是数学中最基本的语言,虽然在高中才正式学习它的知识,但在初中数学的学习中我们已经为学习“集合”积累了丰富的素材,例如“有理数的集合”、“到定点距离等于定长的集合是圆”等有关集合,早已为大家所熟悉.用集合的语言可以深刻地理解函数、数列、曲线与方程的对应关系及其性质;可以明确地表示空间中点、线、面及其位置关系;可以准确地表达方程、不等式、概率与统计中的数量关系.另外,由于“集合”的运算所体现出的逻辑关系,可以有助于对“分类”、“转化”、“数形结合”等数学思想方法的理解,有助于提高逻辑推论能力.因此,用好“集合”的语言,要贯穿于高中数学学习与复习备考的全过程中.
Special Note: “Set ” language is the most basic language in mathematics, although it formally learned its knowledge in high school, but in the study of junior high school mathematics we have accumulated a wealth of material for learning “set ”, for example “Set of rational numbers ”, “to the collection of fixed-point distance equal to the fixed length is round ” and other related set, already familiar to everyone.Using the collection of language can be a profound understanding of the correspondence between functions, numbers, curves and equations And its nature; It can clearly express the point, line, surface and their position in space; Can accurately express the relationship between equations, inequality, probability and statistics. In addition, as the “set ” operation Logical relations can contribute to the understanding of the mathematical thinking and methods such as classification, transformation, mathematical combination and so on, which can help to improve the ability of logical inference.Therefore, "Language, throughout the entire process of high school mathematics learning and review preparation.
