解析几何的基本思想是用代数方法研究几沟,这就沟通了代数和几何两大分支,实现这种把通的基本方法是建立曲线与方程的一一对应,何几何中的点线位置关系转化为方程或不等式的解,曲线的位置关系转化为解方程组与解的讨论.本文拟就这些方面谈谈解题技巧. The basic idea of ​​analytical geometry is to use algebraic methods to study several trenches, which communicates the two branches of algebra and geometry. The basic method to achieve this connection is to establish a one-to-one correspondence between curves and equations. The solution to the solution of the equation or inequality, the positional relationship of the curve is transformed into the discussion of solution equations and solutions. This paper proposes to discuss the problem-solving techniques in these aspects.
