圆锥曲线是高中数学的重要内容,在高考中占有举足轻重的地位.但圆锥曲线的解答题计算量大,尤其是在直线与圆锥曲线的位置关系的题型中,往往需要联立方程组,再进行繁琐的计算才能得到最后结论.这类题型中令许多考生头痛的就是化简计算,往往考生就是在化简计算的过程中产生错误,从而导致失分严重,于是产生较多的“会做却得不到分”的情况.那
Conic curve is an important part of high school mathematics, occupying a decisive position in the college entrance examination. However, the conic is a computationally intensive problem-solving problem, especially in the questions of the linear relationship between the position and the conic curve, often require simultaneous equations, and then The tedious calculations in order to get the final conclusion.This type of question many candidates headache is to simplify the calculation, the candidate is often in the process of simplifying the calculation of the error, resulting in serious loss, resulting in more It will not get points.
