关于 和级数型展开式的规律分析xxxxxx 大学数学与计算机科学学院数学与应用数学专业 2025 级数学班指导老师:xx【摘要】: 众所周知,的幂级数展开形式为: 其中,取时,得到: 下面,我们问:级数 , , , , 是什么
事实上,讨论幂函数级数更为方便,因为我们可以用微积分作工具
对 令 ,由于右端幂级数的收敛半径为:,故对有定义
特别地,当时,有
本文通过计算论证,得出: ,其中是关于的一个次多项式这一结论
将多项式的系数作成一个无穷阶的矩阵: ,文中对矩阵的各行、列、斜方向进行分析、总结,从而得出结论

In fact, research of the power function progression more convenient, because we can use calculus as a tool
For , , due to the radius of convergence of the right end power series are as follows: ,
