高考分值:22分名师指要圆锥曲线在高考中所占分值一般为22分,包括两道小题一道解答题,且解答题以压轴题的形式出现.1.圆锥曲线的方程.解决此类问题的一般方法有:定义法、直接法、待定系数法、相关点法、参数法、交轨法等.2.与圆锥曲线有关的定点、定值、定直线问题.常用的方法:(1)特殊值法.可先取参数的特殊值,再证明当参数变化时,结论成立;(2)参数法.从目标问题对应的关系式的需要引入参数,
College entrance examination scores: 22 points The teacher points to the conic in the college entrance examination scores generally 22 points, including two small problems together to answer questions, and answer questions in the form of pressure axis problems.1.Concircle equations. The general methods of such problems are: the definition of the law, the direct method, to be determined coefficient method, the relevant point method, the parameter method, the rail method, etc. 2. Points and fixed values related to the conic curve, (1) the special value method, the special value of the parameter can be taken first, and then the conclusion is proved when the parameter changes. (2) The parameter method, the parameter is introduced from the need of the relational expression corresponding to the target problem,
