我们平时对解析几何的认识是几何问题代数化,即用代数方法解决几何问题.因此,往往将思路固定在了代数方法而忽略了其本质还是几何问题.事实上,解析几何问题合理的方式是要优先运用几何性质,然后运用代数技巧.就如老师辅导学生一样,因为学生才是主体,若学生自身不努力,那老师的辅导是很艰难的.对于江苏高考,解析几何有其特殊的重要地位,一般是18题,若此题做不好,那分数不但得不高,还会产生焦虑,影响后两道难题.而通过笔者的研究,解析几何问题也是有规可循的.
Our usual understanding of analytic geometry is geometric problem algebra, that is, using algebraic methods to solve the problem of geometry.Therefore, the idea is often fixed in the algebraic method and ignore its essential or geometric problems.In fact, the analytical method of geometric problems is reasonable To give priority to the use of geometric properties, and then use algebraic skills. Just as the teacher counseling students, because students are the main body, if the students do not work hard, then the teacher’s counseling is very difficult.For the Jiangsu college entrance examination, analytic geometry has its special importance Position, generally 18 questions, if this question is not good, then the score is not only not high, but also produce anxiety, affecting the latter two problems.And through the author’s research, the analysis of geometric problems are rules and regulations.
