文章论述了学生在解不等式中,经常遇到已知不等式的解集确定参数值的问题,而常常不得要领,作者从解集区间的端点值方面探索了此类问题,并举例说明,对学生解决此类问题有重要的指导作用。 The article discusses that students often encounter the problem of determining the parameter value of the solution set with known inequalities in solution inequalities, and often can not get the essentials. The author explores such problems from the endpoint value of solution set interval and gives an example to illustrate that for students There is an important guiding role in solving such problems.
