构造函数利用函数思想解决问题,通常着眼于两个变量的对应关系、取值范围、变化规律及其相关性质来研究,运用“联系”和“变化”为主要观点的函数思想方法,来分析和处理问题将会收到意想不到的效果.一、在数列问题中的应用函数的思想贯穿于高中数学教学的始终,在数列内容中有突出的体现,在数学高考中,多次在这一交汇点上设计试题,因此增强使用函数思想方法解决数列问题的意识是十分必要的.例1某城市2001年末汽车保有量为30万辆,预计此后每
Constructor use function thought to solve the problem, usually focus on the correspondence between two variables, the range of values, the law of variation and its related nature to study the use of “contact ” and “change ” as the main point of view of the function of thinking , To analyze and deal with the problem will receive unexpected results.First, the application of the problem in the series of ideas throughout the high school mathematics teaching has always been in the content of the column has a prominent manifestation of the mathematics college entrance examination, many times Therefore, it is very necessary to enhance the consciousness of using the method of thinking of functions to solve the series of problems.Example 1 The number of cars in a certain city was 300,000 at the end of 2001,
