圆锥曲线是平面几何的核心内容,也是学习高等数学的基础,当然是高考命题的热点之一。综观近年来的高考试题,圆锥曲线在高考试题中所占的比重大,远远超过其它各章,且题型、题量、难度保持相对稳定。由于圆锥曲线是中学数学知识的一个重要交汇点,常与 Conic curve is the core of planar geometry, but also the basis for learning advanced mathematics, of course, one of the hot topics college entrance examination. Looking at the entrance examination papers in recent years, the conic curve occupies a large proportion in the entrance examination papers, which far surpasses the other chapters, and questions, questions, and difficulty remain relatively stable. As conic is an important intersection of mathematical knowledge in high school, often with
