Proofs without words are generally pictures or diagrams that help the reader see why a particular mathematical statement may be true, and how one could begin to go about proving it. While in some proofs without words an equation or two may appear to help guide that process, the emphasis is clearly on providing visual clues to stimulate mathematical thought. The proofs in this collection are arranged by topic into five chapters: Geometry and algebra; Trigonometry, calculus and analytic geometry; Inequalities; Integer sums; and Sequences and series. Teachers will find that many of the proofs in this collection are well suited for classroom discussion and for helping students to think visually in mathematics.

a priori intuition...
评分很好玩的一本小書。數學傢的工作基本上是努力發現一般通用的數學方法與規律,或者用數學方法解決一些實例問題。數學愛好者則努力發現更多有意思的數學實例。兼具兩者身份的人太少,所以真正特彆優秀的數學讀物並不多。普通的非數學專業的人,肯定都是更喜歡看有意思的實際例子瞭!
评分神瞭!
评分打印幾頁,在火車上遊戲非常閤適!
评分很有意思很喜歡~~
