含多元的数学问题是高中数学重要题型之一,也是同学们备感头疼的棘手题型.一方面,我们面对题中复杂的数量关系,难以将其中关系全部用数学式子表达出来;另一方面,式子虽然列出来了,但面对这些高次方程组或多元不等式,束手无策,没有清晰的思路.对于这些问题,我们需要精心设计一些有利于理解的问题,自主探究,找到解决问题的办法. Mathematics problems with multiple meanings are one of the important questions in high school mathematics and also a thorny topic for students.On the one hand, in the face of complicated quantitative relations, we can not express all the relations among them in mathematical formulas. On the other hand, although the formulas are listed, in the face of these higher-order equations or multivariate inequalities, there is no clear way of thinking, and for these problems, we need to carefully design some problems that are conducive to understanding, to explore and find solutions The solution to the problem.
