皇上写的数学书 “凡论数度,心始于一点,自点引之而为线,自线广之而为面,自面积之而为体,是各三大纲,是以有长而无阔者谓之线,有长与阔而无厚者谓之面,长与阔厚俱全者谓之体,惟点无长阔厚薄。” 从内容上看,这段话说的是点、线、面积、体积,应该属于几何的范畴。但它所使用的文 The math book written by the emperor “on the number of degrees, the heart starts at a little, from the point of reference for the line, since the line wide and surface, since the area and body, is the three programs, Wide said that the line, there is a long and wide and thick without the person that the face, long and broad-minded person that the body, but the point no long and thin. ”Content from the point of view, this is the point, line, Area, size, should belong to the category of geometry.
