在高中解析几何中,常出现“已知过两条曲线的交点,再结合其他条件来求曲线方程”的题目.该类题目的常规解法是:联立方程组求出交点,再结合其他条件求出曲线方程.本文试图从方程与曲线的关系入手来理清相应的关系,从而给出这种方法的适用条件及解题步骤.
In the high school analytic geometry, often appear “Known intersection of two curves, combined with other conditions to find the curve equation ” The conventional solution to this problem is: simultaneous equations to find the intersection point, combined with other conditions Find out the equation of the curve.This article attempts to start with the relationship between the equation and the curve to sort out the corresponding relationship, and thus gives the application of this method and the solution steps.
