物质世界是运动的,数学从形和数的角度反应运动的规律。所以,对于数学问题,也需用运动、发展的观点去探索,引导学生去观察、去猜想、去发现、去辩析问题的实质和由满足某些条件而产生的新的数学性质和图形状态,于解题之中,逐步掌握证,(解)题的方法和规律,并用之于实践。现以圆锥曲线的问题为例,作如下探索:一、关于直线和双曲线、渐近线相交问题的探索
The material world is a movement, and mathematics reflects the laws of motion from the angle of form and number. Therefore, for mathematics problems, it is also necessary to explore from the perspectives of sports and development, and guide students to observe, guess, discover, and interpret the essence of the problem and the new mathematical nature and graphic state resulting from satisfying certain conditions. , In solving problems, gradually grasp the methods and rules of the (solution) questions and apply them to practice. Now take the conic curve problem as an example, as follows: First, the exploration of the intersection of straight line, hyperbola and asymptote.
