On Several New Methods to Proof Combinatorial Identities

运用分类法、概率法和求导法则对几个重要的组合恒等式进行了证明 ,从而避免了组合恒等式常见证法的繁琐性 。

There are many ways to verify combinatorial identities. The normal ways to verify it involve complex processes. In this paper, instead of using the normal ways, it uses classification, probability and derivation calulas to verify several important combinatorial identities, thus simplify the processes.
