论文部分内容阅读
中学生在学习了方程、不等式和函数以后简单问题会作了,但是大多数同学把这三部分内容仍然割裂孤立地理解。所以,有必要通过例子把这三部分内容的内在联系讲明。这样对学生是有好处的。
The middle school students will do simple questions after learning the equations, inequalities and functions, but most of the students still understand the three parts of the content separately and separately. Therefore, it is necessary to clarify the internal links of these three parts through examples. This is good for students.
