摘要:通过对已知恒等式sum[2nn]from n=0 to ∞x^n=1/(1-4x)展开和微分,推导出几个新的组合恒等式,并通过计算高阶导数推得一般情况,使前面几个组合恒等式得到了统一,得到一组新的组合恒等式。
In this paper,through the expansion and differentiation of the known identity we derived several new combinatorial identities,and by calculating higher order derivatives we get the general condition,so we make the new combinatorial identities unified,we got series new combinatorial identities.
