热点之一圆锥曲线的定义、圆锥曲线方程圆锥曲线定义是其一切几何性质的“根”与“源”,是建立曲线方程的基础,揭示了圆锥曲线上的点与焦点及准线间的关系,是解析几何综合题的重要背景·圆锥曲线的方程是研究几何性质的重要载体·热点之二函数与方程的思想函数与方程的思想是贯
One of the hot spots Conical curve definition, conic curve equation Conic curve definition is the “root” and “source” of all its geometric properties. It is the basis for establishing the curve equation and reveals the relationship between the point on the conic curve and the quasi-line. , is an important background for the analysis of geometric synthesis problems. The equation of the conic section is an important carrier for the study of geometric properties. The second hot point is the idea of the function and equation of the function and equation.
