Several Proofs for a Calculus Problem

LU Hanchuan (Schoof Mathematics and Information Science,Shaanxi Normal University,Xi'an 710062,PRC)  
By generalizing,this paper gathers several proofs for a calculus problem,and extends the conclusion to a general topological space.The thinking process shows how the topological theorem is concluded,which is an inspiring example for innovative thinking.
