摘要
主要介绍如何运用拉格朗日中值定理、函数的单调性、函数图形的凹凸性、估计积分值等微分学的方法来证明不等式。
This essay introduces mainly how to calculate some special definite integral through the integral calculus property of even and odd function in symmetrical interval, the integral property of periodic function, the geometrical meaning of the definite integral, and the methods and skills of resolution and combination of integrand.
