1本单元重点、难点分析本单元的重点是各种类型不等式的解法,解不等式的关键是要善于根据有关性质或定理把原来形式比较复杂的不等式(组)等价变形为与之同解的相对简单一些的不等式(组),正确地进行同解变形是关键,同解变形的思路一般为:超越不等式变形为代数不等式,无理不等式? 1 Key and Difficulties Analysis of this Unit The focus of this module is the solution of various types of inequalities. The key to solving inequalities is to be good at equating the more complex inequalities (groups) of the original form to solutions of the same in terms of properties or theorems. Relatively simple inequalities (groups), the correct solution to the deformation is the key, the same solution distortion is generally: transcendental inequality deformation algebraic inequality, irrational inequality?
