在高中平面解析几何中,“降维”转化的思想非常重要.象我们所熟知的将三维立体几何问题转化为二维平面几何问题一样,平面解析几何往往将二维问题转化到一维坐标轴上解决问题,这就是降维转化思想.应用“降维”转化的思想,可简化解题思路,使计算方便快捷.
In high-level plane analytic geometry, the idea of “dimension reduction” transformation is very important. As we know, transforming three-dimensional geometric problems into two-dimensional plane geometry problems, plane analytic geometry often transforms two-dimensional problems into one-dimensional coordinate axes. To solve the problem, this is the idea of reducing dimensionality and transforming ideas. Applying the idea of “dimensional dimension reduction” can simplify the problem-solving ideas and make calculations easier and faster.
