【前端分析】沪教版高中数学教材把二项式定理安排在高三年级第16章第5节。它既是安排在排列组合内容后的自成体系的知识块,也是初中学习的多项式乘法的一个自然推广。它与后面学习的概率的二项分布有着内在的联系,利用二项式定理还可以进一步深化对组合数的认识,又是解决整除、近似计算、不等式证明的有力工具,同时也是后面的数学期望等内容的基础
[Front-end analysis] Shanghai high school mathematics teaching textbook to put the binomial theorem in the third grade Chapter 16 fifth. It is not only a self-contained knowledge block arranged in the composition of the portfolio, but also a natural extension of polynomial multiplication in junior high school learning. It is intrinsically linked to the binomial distribution of probabilities of learning, and the binomial theorem can further deepen the understanding of the number of combinations. It is also a powerful tool for solving divisibility, approximate calculation, and proving inequalities, and is also followed by mathematical expectation The basis of such content
