中学数学里 ,用平移和伸缩变换重点研究了三角函数的一些性质 ,本文将它推广到一般的抽象函数中 ,可研究一些抽象函数的性质 .它有很多应用 ,如 2 0 0 3年江苏省高考18题 ,就可应用这种方法来解 ,且解法显得非常简捷 .1 复合平移伸缩变换设函数Ｃ1 ∶ ｙ =ｆ(ｘ)和Ｃ2 ∶ ｙ =
In middle school mathematics, some properties of trigonometric functions are studied with translation and scaling. This article generalizes it to general abstract functions and can study the properties of some abstract functions. It has many applications, such as Jiangsu Province in 2003. College entrance examination 18 questions, you can apply this method to solve, and the solution is very simple. 1 compound translation scaling function C1: y = f (x) and C2: y =
