二项式定理的应用很广,也很重要。其重要性主要表现在两个方面:第一:它所揭示的方法富有启发性;第二:它与高等数学联系紧密。学习它,既有利于训练我们的思维,也有利于今后进一步学习。限于篇幅,本文仅从四个主要方面介绍二项式定理的应用,希望同学们阅读本文时,把重点放在方法、原理上,做到举一反三,开拓视野。 The binomial theorem is widely used and important. Its importance is mainly reflected in two aspects: First, the method it reveals is instructive; Second, it is closely related to higher mathematics. Learning it is not only conducive to training our thinking, but also conducive to further study in the future. Due to space limitations, this article only introduces the application of the binomial theorem from four major aspects. I hope that when students read this article, they will focus on the methods and principles, and that they will do their best to expand the horizon.
