解析几何是高中数学的重点,也是难点,知识点非常多,运算要求特别高,所以学生遇到解析几何的问题非常畏惧,但教师如果在平常教学中善于总结、分类知识点,就会激发学生的兴趣。本人就一类切点的连线问题与之共勉。 Analytic geometry is the high school mathematics focus, but also difficult, the knowledge point is very large, the computing requirements are particularly high, so students encounter the problem of analytic geometry is very scared, but teachers in normal teaching are good at summing up, classification of knowledge points, it will inspire students interest of. I talk about a kind of point of connection with the encouragement.
