有些椭圆问题,若分开讨论其运算量大,如注意其整体结构特点,设法将问题整体变形转化,以达到避免一些不必要的运算,降低解题难度.一、整体分析,寻找捷径对于有些椭圆问题,若能从整体入手分析问题的实质,就能找出解决问题的最佳途径. Some elliptic problems, if separately discussing the large amount of computation, such as paying attention to the overall structural characteristics, try to transform the overall deformation of the problem, in order to avoid some unnecessary operations, to reduce the difficulty of solving problems., First, the overall analysis, find a shortcut For some oval If we can analyze the essence of the problem from the whole, we can find out the best way to solve the problem.
