导数在研究函数性质的问题当中起着十分重要的作用,尤其是在处理函数性质和不等式有关的综合性问题当中,导数往往扮演着重要的角色,需要利用导数作为工具得出函数性质,从而解决不等式问题。(一)利用导数得出函数的单调性来证明不等式1.直接构造函数,然后再运用导数来推导出函数的单调性,以此证明不等式成立。
Derivatives play a very important role in the study of the nature of the function. Especially in dealing with the comprehensive problems related to the nature of the function and the inequality, derivatives often play an important role. Derivatives need to be used as tools to derive the properties of the function, so as to solve the problem Inequality problem. (A) the use of derivatives of monotonicity to prove the inequality 1. Direct constructor, and then use the derivative to derive the monotonicity of the function, in order to prove that the inequality holds.
