数学符号语言是数学的特殊语言,它不仅能非常简明和比较直观地表示出数量间的内在关系,而且对其关系能表示得十分准确和深刻.但由于它的抽象性,在运用中稍有疏漏就会产生错误.因此,准确理解和掌握数学符号语言是正确运用它的前提.普通高校招生全国统一考试《数学科说明》中明确要求“理解函数(函数的记号、定义域、值域)及其有关的概念,掌握互为反函数的函数图象的关系”.历年高考和数学竞赛中也常常出现这类题目.所以,在实际运用中准确理解和掌握符号语言у=∫(χ)、у=∫[(?)(χ)]和у= ∫~-1[(?)(χ)]是十分重要的.下面就笔者所见所闻来谈谈这方面的问题.
The mathematics symbolic language is a special language of mathematics. It can not only show the internal relations between numbers in a very concise and intuitive way, but also can represent its relationship very accurately and profoundly. However, because of its abstractness, it is slightly used in the application. Missing errors will result in errors. Therefore, accurate understanding and mastery of the mathematical symbolic language is the premise for the correct application of it. The Unified National Examination for Higher Education Enrolment “Mathematics Section Explained” clearly requires “understanding function (function notation, domain, value range). And related concepts, grasping the relationship between functional images that are mutually anti-functions.” This type of problem often occurs in college entrance examinations and math competitions over the years. Therefore, in the actual application, the symbolic language is accurately understood and understood. , у = ∫ [(?) (χ)] and у = ∫ ~ -1 [(?) (χ)] is very important. Here’s what the author has seen and heard to talk about this issue.
