运用数形结合思想处理问题,就是根据数学问题和结论之间的内在联系,既分析其代数含义又揭示其几何意义,使数量关系和空间形式巧妙、和谐地结合起来,并充分利用这种“结合”寻找解题思路,使问题得到解决。 The use of the idea of ​​combining numbers and shapes to deal with problems is based on the intrinsic relationship between mathematical problems and conclusions. It not only analyzes the algebraic meanings but also reveals their geometric meanings. It makes the quantity relations and spatial forms combine ingeniously and harmoniously, and makes full use of this. Combine with “looking for problem-solving ideas” to solve the problem.
