1一道数学历史名题:卡丹旋轮问题(Cardan sSpur Wheel Problem)一个圆盘沿着半径为其两倍的另一个圆盘的内缘滚动时,这个圆盘上标定的一点所描出的轨迹是什么这个有趣的问题看似平凡,其实大有来头,是一道数学历史名题.意大利数学家卡丹(Cardano,1501~1576)设计了一个所谓“卡丹
1. A Mathematical History Title: Cardan sSpur Wheel Problem When a disc rolls along the inner edge of another disc twice its radius, the locus trace of a point marked on the disc What is this interesting question seems trivial, in fact, a great precedent, is a mathematical history.Cardan mathematician Cardin (Cardano, 1501 ~ 1576) designed a so-called "Cardin
