文 [1]例说了创造性思维方法中的“改变观点”的技巧 ,读罢很受启发 .由于概率统计将列入高中数学的教学内容[2 ] ,将传统的某些数学教学内容试改以概率观点来研究和处理将别有一番趣味 ,本文将对文 [1]所创造的 5个新问题给以概率证明 .新问题 1 若 cos2 α1 +cos2 α2 +… +
The article [1] describes the “change of view” technique in the creative thinking method. Reading is very inspiring. Because probability statistics will be included in the teaching content of high school mathematics [2], some of the traditional mathematics teaching content will be changed. It will be interesting to study and deal with the probabilistic point of view. This article will give probabilistic proof of the five new problems created by [1]. New problem 1 if cos2 α1 + cos2 α2 +... +
