我们常把映射x→y=f(x)中满足α=f(α)的α称为不动点,它是研究映射时一个很重要的性质,由于中学数学中函数、数列等都与映射有关,因而若存在不动点α,可借助α来研究许多数学问题,特别是非线性问题,下面笔者介绍一些用不动点来解非线性问题的方法,可供大家参考.1数列递推若递? We often call the α satisfying α=f(α) in the mapping x→y=f(x) as a fixed point, which is a very important property when studying the mapping. Because of the mapping of functions, sequences, etc. in middle school mathematics, Relevant, so if there is a fixed point α, can use α to study a lot of mathematical problems, especially non-linear problems, the following author describes some methods to solve nonlinear problems with fixed points, for your reference. 1 series recursive Handing?
