近年来“强调基础、能力立意、在知识网络交汇点处设计试题”已经成为最近几年高考试题的主要特色.因此,我们在学习中,应该关注并研究数学交汇问题的求解,以开拓视野,进一步提高数学的思维能力.特别是2013年高考中出现的几个新的交汇点应引起大家的注意,它们是:一、函数与二项式定理 In recent years, “emphasize the foundation, ability conception, the design of knowledge network intersection” has become the main features of the college entrance examination papers in recent years, therefore, we should pay attention to and study the solution of the mathematical intersection problem in order to explore Horizons, to further improve the ability of thinking in mathematics, especially in 2013 college entrance examination appeared in several new junctions should cause everyone’s attention, they are: First, the function and binomial theorem
