给出含有导数式子的等式或不等式,判断一类等式或不等式是否成立,这类问题常常需要利用导数的运算法则构造函数,然后利用导函数的性质解决问题.下面我们举例说明.
Given equations or inequalities with derivatives, determining whether a class of equations or inequalities hold holds often requires the use of derivatives of the algorithms to construct functions, and then uses the nature of derivative functions to solve the problem.
