一元二次方程和二次函数是初中数学中比较重要的知识块,而到高中数学也是非常重要的2个内容.但根据现在的初中和高中课程标准下编写的教科书中,一元二次方程、二次函数部分的衔接上还是存在着问题,本文根据目前高中数学中所需要的有关知识和能力点(初中还没充分涉及或完全没有涉及到)进行加强或补充.
The quadratic equation and the quadratic function are one of the more important blocks of knowledge in junior high school mathematics, and it is also very important to go to high school mathematics. However, according to textbooks written under the current junior high school and high school curriculum standards, the one-dimensional quadratic equation, There is still a problem in the connection of the quadratic function part. This paper reinforces or supplements according to the relevant knowledge and ability points needed in the current high school mathematics (the junior high school has not fully involved or not involved).
