两类有理分式的高阶导数

摘要

This paper studies higher derivatives for two of derivative formulas. With these formulas, the original tives for relevant rational fractions. kinds of rational fractions and obtains two groups operation will be simplified to get higher derivatives for relevant rational fractions.%讨论两类有理分式的高阶导数的求法，得到了两组导数公式。用公式求相应的有理分式的高阶导数。能起到较好的简化作用。
