众所周知,直线与圆锥曲线的位置关系在高中数学中占据重要的位置。直线的参数方程在解决此类问题有着非常重要的作用。本文通过对直线参数方程两种形式进行对比,体现参数方程在解题中的作用。
It is well known that the positional relationship between straight lines and conic curves occupies an important position in high school mathematics. Linear parametric equations play a very important role in solving such problems. This article compares the two forms of linear parameter equations to reflect the role of parametric equations in solving problems.
