9 . 第二十五届中国国际高新技术成果交易会(简称“高交会”)在深圳闭幕.会展展出了国产全球首架电动垂直起降载人飞碟.观察它的外观造型,我们会被其优美的曲线折服.现代产品外观特别讲究线条感,为此我们需要刻画曲线的弯曲程度.考察如图所示的光滑曲线
上的曲线段
,其弧长为
,当动点从
沿曲线段
运动到
点时,
点的切线
也随着转动到
点的切线
,记这两条切线之间的夹角为
(它等于
的倾斜角与
的倾斜角之差).显然,当弧长固定时,夹角越大,曲线的弯曲程度就越大;当夹角固定时,弧长越小则弯曲程度越大,因此可以定义
为曲线段
的平均曲率;显然当
越接近
,即
越小,
就越能精确刻画曲线
在点
处的弯曲程度,因此定义
(若极限存在)为曲线
在点
处的曲率.(其中
,
分别表示
在点
处的一阶、二阶导数)
的焦点到准线的距离为3,则在该抛物线上点
处的曲率是多少?
(2)若函数
,不等式
对于
恒成立,求
的取值范围;
(3)若动点
的切线沿曲线
运动至点
处的切线,点
的切线与
轴的交点为
.若
,
,
是数列
的前
项和,证明
.
