一、学习二项式定理的意义二项式定理在初等数学的学习中起着承上启下的作用。它可对初中学习的多项式的变形起到复习、深化的作用;利用二项式定理可得到关于组合数的一些恒等式,从而深化对组合数的认识;二项式定理与概率理论中的二项分布有其内在联系,是进一步学习概率统计的准备知识;二项式定理是解决某些整除性、近似计算等 1. The Meaning of Binomial Theorem The binomial theorem plays a role in the learning of elementary mathematics. It can play a role in reviewing and deepening the polynomial transformation of junior high school learning; using binomial theorem can get some identities about the combination number, so as to deepen the understanding of the combination number; binomial theorem and two items in probability theory. The distribution has its intrinsic connection, which is the preparation for further study of probability statistics; the binomial theorem is to solve certain divisibility, approximate calculations, etc.
