众所周知 ,解答解析几何问题过程的繁简程度 ,往往受制于解题途径的选择 ,笔者在近几年高考阅卷中发现 ,有不少考生因选择解题方法不当 ,而导致解答过程繁杂、计算量大 ,甚至半途而废 .本文笔者根据自己体会 ,结合近年来高考试题 ,就解答解析几何试题常用的求解途径例释如下 , As we all know, the complexity of the process of solving analytical geometric problems is often constrained by the choice of problem-solving approaches. In recent years, the author found that many candidates have chosen improper solutions because of their improper choice of solutions. Large, and even half-way. The author of this paper according to their own experience, combined with the examination questions in recent years, to solve the analytical solution of geometric problems commonly used solution examples are as follows,
