摘要
利用二次曲线焦点弦,给出二次曲线幂定理统一的代数形式和几何模型,并且利用该结论,推广《数学通报》数学问题解答2392和2396题的结论.
This paper gives the unified algebraic form and geometric model of the theorem with geometric straight square form of conic curve by using the conic focus chord,and generalizes the conclusion of solving 2392 and 2396 problems in mathematical problem of Shuxue Tongbao by using this conclusion.
