请教：如何画复杂二维曲线？？

legna

    现想在CAXA的任意一款软件里画出如下二维曲线：

<img src="attachments/dvbbs/2003-12/200312101745381925.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003-12/200312101745381925.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

   请问该如何画？？谢谢！！

我知道在CAXA里有输入公式曲线的地方，但好像不能输入指数函数？？

haubest

可以输入指数函数，exp(x)

好像应当先化成参数方程。

好，我试试看。

你的方法我试验过了，好像不行。在输入方程之后，一点确定就死机。我不知道为什么。
你能不能画出来给我看看？？谢谢了！

楼上：不瞒你说，你的方法是我目前找到的最好的方法了，现在能画出来部分的曲线，但是还是经常死机！！这到底是为什么呀？？到现在我还没完成呢，明天就要交了！！
