圆锥曲线的几何性质,深刻直观地揭示出圆锥曲线的本质属性,是解析几何中的“灵魂”。在解题中,若能灵活运用圆锥曲线的几何性质,在数形结合中解决问题,可以避免繁杂的代数推理运算,起到化繁为简、直观简洁的效果。现以近两年高考试题为例,探讨圆锥曲线几何性
The geometric nature of the conic curve reveals the essential properties of the conic curve profoundly and intuitively, and is the “soul” in analytical geometry. In the problem-solving problem, if we can flexibly use the geometrical properties of conic curves and solve the problems in the combination of numbers and shapes, we can avoid the complicated algebraic inference operations and achieve the effect of simplifying and simplifying the visualization. Now taking the exams in recent two years as an example to discuss the geometry of conic curves
