著名数学家华罗庚曾说过:“数形结合百般好,割裂分家万事休.数形结合,数是基础,形是关键,既要以形助数,又要以数定形.”解题教学中我聆听大师的教诲,常根据某些数学问题的结构和形式,恰当、巧妙地构出距离,借助其图形解题,常可捕捉到解题的机智,获得新颖、独特、简捷的解法,曲径通幽,回味无穷! Well-known mathematician Hua Luogeng once said: “The perfect combination of numbers and shapes, the separation of all things break off.” Combination of numbers, the number is the foundation, the shape is the key, it is necessary to form the number of assistance, but also the number of shape. In my teaching, I listened to the teachings of the masters and used the structure and form of some mathematical problems to formulate the distance properly and cleverly. With the aid of their graphic solutions, I could often capture the tactics of problem solving and obtain new, unique and simple Solution, winding path, aftertaste!
