利用“补集思维法”解决数学问题

Solving Mathematics Problems Using "The Complementary Set Thought Method"

利用集合思想解题是中学数学解题中一种重要思维方式,其中"补集思维法"又是集合思想的一种重要体现,它往往能使复杂问题简单化,能够把从正面难以解决的问题从反面有效、快速地加以解决.教学中应加强学生的训练,从而提高学生分析问题、解决问题的能力.

＂The Complementary Set Thought Method＂ is a key express in the set viewpoint which is one of the most important methods to solve mathematical problems in the secondary school. ＂The Complementary Set Thought Method＂ usually can simplify the complex problem, and can solve the problem effectively and quickly from the opposite way. Therefore, the teacher should strengthen the students＇ training on this method in mathematical teaching to enhance the students＇ ability of analyzing and solving problems.
