Development and comparison about the proof of sphere\rq s volume by Chinese and Japanese mathematicians. (Chinese. English summary)

J. Math. Educ. (Tianjin) 18, No. 1, 16-21 (2009).

Summary: The proof of the sphere\rq s volume formula has been dealt with by both Chinese and Japanese mathematicians. The method used in proofing the sphere\rq s volume formula by Japanese mathematicians shows excellent coherence and the sphere\rq s volume formula has been developed by several mathematicians. But some different methods are used to proof the sphere\rq s volume formula by Chinese mathematicians.
