摘要
《中学数学研究》2016年第5期的《圆锥曲线"中点弦"的一个判定定理及其应用》中的定理应用范围只局限于椭圆和双曲线领域,本文进一步将圆锥曲线"中点弦"的判定定理拓展到抛物线的领域。
"Middle school mathematics study" in 2016 fifth the "Conic " midpoint chord " of a theorem and its application" in the scope of application of theorem is confined to elliptic and hyperbolic field, this paper further expands the theorem of conic curve "midpoint chord" to the field of parabola.
