学习了一次函数与反比例函数以后,会遇到一些一次函数图象与反比例函数图象及两坐标轴相交这一类问题,这类问题中有一个基本的结论——线段相等问题,或者说三角形全等问题,这个基本结论可以说是隐性的,因为它具有隐蔽性,通常被人们所忽视,也不易发现,只有认真探究才能挖掘出来.这个基本的结论具有普遍的实用性,可给解决一些一次函数图象与反比例函数图象结合的有关题型带来巨大方便,尤其是做客观性试题时可直接应用这个结论.下面例析这个基本结论的
After learning the first order function and the inverse proportion function, we encounter some problems that the first order function image intersects with the inverse proportion function image and the two coordinate axes. One of the basic conclusions of this kind of problem is that the line segments are equal, that is, the triangle The basic conclusion can be said to be recessive, because it is hidden, it is usually neglected by people, it is not easy to find it, and only careful exploration can dig it out. This basic conclusion has universal practicability and can be solved Some of the first-order function images and inverse-proportion function images combined with the relevant questions of great convenience, especially when doing objective questions can be applied directly to this conclusion. The following analysis of this basic conclusion
