数形结合是一个数学思想方法,包含“以形助数”和“以数辅形”两个方面,由此,其应用大致也就可以分为两种情形:或者是借助形的生动和直观性来阐明数之间的联系,即以形作为手段,数为目的,比如应用函数的图像来直观地说明函数的性质;或者是借助于数的精确性和规范严密性来阐明形的某些属性,即以数作为手段,形作为目的,如应用曲线的方程来精确地
The combination of number and shape is a mathematical way of thinking, which includes two aspects of “form auxiliary ” and “number auxiliary ”. Therefore, its application can be roughly divided into two situations: Vivid and intuitive to clarify the connection between the number, that is shaped as a means, the number of purposes, such as the application of the function of the image to intuitively illustrate the nature of the function; or by means of the accuracy of the number and specification tightness to clarify Certain attributes of the shape, that is, the number as a means of shape as an objective, such as the application of the curve equation to accurately
