摘要
导数的极限定理是数学分析中较重要的一个定理,既是导数的性质之一,又是求函数导数的工具.将导数极限定理推广到了高阶导数、偏导数、方向导数,从而得到了求高阶导数、偏导数以及方向导数的一个重要工具.
The derivative limit theorem is an important theorem in mathematical analysis, which is both a property of the derivative, and also a tool of seeking function derivative. In this paper, the derivative limit theorem is elevated to the higher order derivative, partial derivative, directional derivative. Thus an important tool is obtained for high order derivative, partial derivative and directional derivative.
