一、数形结合思想数形结合是中学数学中四种重要思想方法之一,对于所研究的代数问题,有时可研究其对应几何的性质使问题得以解决(以形助数);或者对于所研究的几何问题,可借助于对应图形的数量关系使问题得以解决(以数助形),这种解决问题的方法称之为数形结合。 I. Combination of Number-Shape and Combination of Thoughts Number-one combination is one of the four important thinking methods in middle school mathematics. For the algebraic problems studied, sometimes the nature of the corresponding geometry can be studied to solve the problem The geometry problem studied can solve the problem by means of the quantity relationship of the corresponding figures (in the form of numbers), and the solution to the problem is called the combination of number and shape.
