[求助]有关绘包络线及计算面积的问题
<P>已知,xy坐标系中一组点的坐标</P><P>求出并显示出这组点的包络线,并求包络线所围的面积</P>
<P>请问各位达人这个怎么实现?</P>
<P>附上示意图</P><img src="attachments/dvbbs/2005-6/200565214913771.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/2005-6/200565214913771.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
<P>呵呵,这是算法(嗯应当说是计算)的问题呀,程序没什么技术含量呀</P> <P>对呀</P><P>就是问怎么计算</P> <P>Analyze中的数学工具里是否有关于这个的?</P> 呵呵,好像高等数学里面有吧,翻翻书看看了
