初期和算之锥率1/2.96探源

Study on the Source of Rate 1/2.96 in Calaculating Volume of Pyramid of Wasan in the Early Edoperiod

对和算锥体体积算法中之锥率12.96的来源问题进行了探讨,在对中日相关数学史料分析的基础上,提出新的算法复原方案,并指出了它与中算之间存在的联系.

The problem of source of the rate 1/2.96 engaged by Japanese mathematicians in calculating volume of pyramid in early period is treated. Based on analysis of historical materials and mathematical principle in Wasan and Chinese traditional mathematics, a new scheme is proposed.
