曲线的渐近线的确定

DETERMINATION OF THE ASYMPTOTIC LINES TO A CURVE

本文给出了曲线的渐近线的定义,得到了用极限确定曲线的渐近线的若干方法,进而提出了利用导函数的极限以确定某类曲线的渐近线的方法,从而为函数的作图带来了方便。

This paper introducesnthe definition of the asymptotic lines to a curve and obtains several methods to determine these lines. For a certain kind curves, one can do this by using the Limitation of the derivative func tions
