反函数微分性质的逆命题

在分析了积分法是微分法逆运算的基础上，提出了反函数微分性质的逆命题，由此得到两人定理和一个推论，并进一步指出这种新的积分方法对于求解高次方的三角函数的积分常常十分有效。

An Inverse Proposition for Differential Properties of Inverse Function

On the basis of analyses that an integral operation is the inverse operation of a differential operation, we propose an inverse proposition for differential properties of inverse function and two theorems with a corollary. Finally, we point out that the new integral methods are often very effective to calculate integral of the triangle functions with higher powers.
