刘徽割圆术,π与极限■(Sinx)/x

CYCLOTOMIC METHOD OF LIU HUI,π AND (?) (sinx)/x

本文应用微积分学中重要极限之一:(?)(Sinx)/X=1,给出了我国古代刘徽割圆术及π的古代近似计算方法根据的简捷证明,愿本例在说明高等数学知识对中学教材“居高临下”的作用上能起到抛砖引玉之效。

In this paper,we give a simple proof of cyclotomie method of Liu Hui and ancient times approximate calculation for π,The essential limit of infinitesimal calculus:(?)(sinx)/x=1 are used by the proof.
