有些数学问题,若从正面去进行分析,常常感到十分繁难,甚至一筹莫展.这时若改变思维习惯,取其反面进行思考,会有出奇制胜的效果．运用补集思想是这种思维方式的较好体现．以下举例谈谈补集思想在解题中的运用,供同学们参考和借鉴．例1已知二次函数f(x)=4x2-2(p- Some mathematics problems, if analyzed from the front, are often very arduous and even unprepared. At this time, if you change your thinking habits and think from the wrong side, you will have the effect of surprisingly winning. The use of complementary thinking is a better reflection of this way of thinking. The following example talks about the use of complementary thoughts in problem solving for reference and learning from the students. Example 1 is known as a quadratic function f(x)=4x2-2(p-
