解析几何的一大特点就是计算量大,如何简化计算?学生和老师都在努力寻找解决的方法.对于一道解析几何问题,几乎每位学生都说“会”——学生基本上都能找到解题的切入口,找到解题的思路,能否正确算出来是另一回事.对于一道题目,如何快速找到计算量小的解题思路呢?本文谈谈如何结合定点,简化计算,快速求解.众所周知,直线过定点的题目,是基本题目,对于某些特定的直线方程形式,能很快地找到直
One of the major features of analytic geometry is that it takes a large amount of computation and simplifies computation. Students and teachers are struggling to find solutions. Almost every student says ’analytic geometry’ Find a solution to the problem, find a solution to the problem, can be calculated correctly is another matter.For a topic, how to quickly find a small amount of computation problem-solving ideas? This article talks about how to combine fixed-point, simplify the calculation, Fast solution. As we all know, over-fixed point subject is the basic problem, for some specific forms of linear equations, can quickly find straight
