解析几何中的定值、定点、定线以及定曲线等问题一直是江苏近几年来高考中的热点问题,江苏各大市的统考、模拟基本上都是保留题。难度中等偏上,很多考生都感到很棘手,即使有思路,但迫于计算量大,计算要求高,基本上都是得些基本分,剩余的只能望题心叹了。基于这种情况,这就要求我们老师平时就要渗透解析几何不可怕的思想,并在实际教学中加强研究,把最普通、最简洁的解题方法与学生分享,并能推广应用,最终取得高考的胜利。
Analytic geometry in the fixed value, fixed-point, alignment and fixed curve and other issues has been the Jiangsu college entrance examination in recent years, hot issues, major cities in Jiangsu unified test, the simulation are basically reserved questions. Moderate upper difficulty, many candidates feel very difficult, even though there are ideas, but forced a large amount of computing, computing requirements are basically some basic points, the rest can only look sigh. Based on this situation, this requires that our teachers usually want to infiltrate the idea of analytic geometry is not terrible, and in the actual teaching to strengthen research, the most common and most concise problem-solving methods to share with students, and can promote the use of, and ultimately obtain College entrance examination victory.
