【摘要】 给定隐函数方程F(x,y)=0,要作出它的图形是一桩不容易的事,迄今虽有论著提及它,但按文献所提供的方法想作出某些复杂的曲线,仍有不少的困难,本文给出了一种新的方法——利用切向量旋转的方法来作隐函数曲线的图形,收到了理想的效果。更多还原

【Abstract】 It is not easy to drow a diagram according to a given implicit function F(x. y) = 0,Although there are some works have discussed it.it is still difficult to make the diagram according to the method provided by the refeieuces. This article provide a new meansdraw the implicit function curve by Rotate the tangential vector. It would achieve a pexfect impression.更多还原
