Abstract: "number" and "form" is a difficult point in middle school mathematics knowledge, at the same time is also the most important element in the analytic geometry. China's famous mathematician hua luogeng said: "the number shape good every possible way, split between split everything." So, if you want to study to lay the solid foundation for middle school mathematics, number must be used to cultivate the thinking method of combining the ideas to solve the problem. Number shape union thinking method has extensive application in the middle school mathematics, such as the number form combining ideas can be used to solve the problem, functions, linear programming problems, solid geometry problems. This paper illustrates several form combining ideas in the application of the analytic geometry. Keywords: the number form combining ideas; Analytic geometry. With several solution form; In order to help function; Number of conformal transformation.望采纳!
