This article takes the teaching of conic sections as an example. By designing worksheets, teachers can introduce the historical material about conic sections to students. By way of using Apollonius' definition of parabola, ellipse and hyperbola, teachers can introduce the geometric aspect of "conic section" to students. By using the concept of " latus rectum " in Conics , we can connect "conic sections"-- representation of geometrical aspect, with "the equation of conic sections"-- representation of algebraic aspect to improving insufficiency of text books.
同时本文也试著从历史文本中寻找材料,简单举例说明数学教师可以如何应用这些史料在几何单元教学上,例如三角函数的正余弦定理,最后再以圆锥曲线的正焦弦为例,说明如何利用数学史料於此单元的教学,尤其是阿波罗尼斯的《锥线论》中对圆锥曲线的3个命题,将此3个命题的内容与意涵,尤其是正焦弦在圆锥曲线的几何意义上所扮演的角色,将其适当地融入教学中,将可使学生真正学习圆锥曲线的几何知识,而不再只是代数形式的几何知识。

Making use of I1 ,I2 ,I3 position Centrifugal rate e and half focal chord p can be calculated. Therefore its easy to transform the equation of the right - angled coordinate branch into polar coordinate equation.
利用I1,I2,I3可以计算出离心率e和半正焦弦p因而可以很容易的直接把直角坐标系中的方程转化为极坐标方程。
