摘要
;通过具体实例,阐述了不动点定理在积分中值定理的证明、判断递归数列的收敛性、计算复杂方程的根以及抽象的函数表达式求解等高等数学问题中的应用.
Through concrete examples,the application of fixed point theorem in the proof of integral mean value theorem,the convergence of recursive sequence,the calculation of complex equation root and the solution of abstract function expression are expounded.
