摘要
本文介绍了函数的图表示法,引入了对图的求导运算,并根据复合函数的求导法则,推出了在图论意义下的链导规则,最后以实例说明这种方法比分析方法具有形象直观,简单易行的显明特点.
In this paper,we introduce the graphic representation of func- tion and differential calculus for graphs. Moreover,we obtain the chain rule for differentiation in the graph sense according to rule of derivation of function. Finally, we illustrate obvious characte- ristics of this method, which is much more simple and clear than analytic method.
