| 摘 要： | 本文给出了一元函数微分学中一个求导运算法则。此法则是用多元函数微分的方法来运算一元函数的导数,并从理论上给出了严格的证明。这样,便把一元函数与多元函数的微分法统一了起来。利用此法则运算某些函数的导数也起到了简化作用。

| Abstract: | In this paper, a rule for derivation of fanction of a single variable in calculus is given. By the rule a deriva- tive of a function of a single variable can be obtained by the derivation of the function of many variables. Be- sides, a strict proof of this rule is also glven theoretically. Thus, the differentiation of a function of a single va- riable and of several variables are unified. Using this rule, the calculation of the derivative of soma functions can also be simplified. |
