方法一数形结合法就是通过数与形之间的对应和转化来解决数学问题,它包含以形助数和以数解形两个方面.利用它可使复杂问题简单化、抽象问题具体化.它兼有数的严谨与形的直观之长,是优化解题过程的重要途
The method-numeric combination method solves the mathematics problems through the correspondence and transformation between numbers and shapes. It contains two aspects: the form-assisted number and the number-decomposing form. The use of it can simplify complex problems and concretize abstract problems. It has the rigorousness and intuition of numbers and is an important way to optimize the problem solving process.
