函数解析式y=f(x)和二元方程F(x,y)=0是高中数学中的两大学习重点,也是学习难点.大部分学生在学习这两个知识点时,往往将它们看作两个相互独立的知识点来学习,没有体会到它们之间的密切关系,这样不但反映了对数学知识理解上的欠缺,而且也阻碍了数学综合解题能力的提高.实际上, The function analytical formula y=f(x) and the binary equation F(x,y)=0 are two major learning priorities in high school mathematics, and are also difficult to learn. Most students often learn about these two knowledge points, often As two independent knowledge points to learn, do not appreciate the close relationship between them, this not only reflects the lack of understanding of mathematical knowledge, but also hinder the improvement of mathematical comprehensive problem-solving ability. In fact,
