1 . 阅读知识卡片,结合所学知识完成以下问题:知识卡片1:一般地,如果函数
在区间
上连续,用分点
将区间
等分成
个小区间,在每个小区间
上任取一点
,作和式
(其中
为小区间长度),当
时,上述和式无限接近某个常数,这个常数叫做函数
在区间
上的定积分,记作
即
.这里,
与
分别叫做积分下限与积分上限,区间
叫做积分区间,函数
叫做被积函数,
叫做积分变量,
叫做被积式.从几何上看,如果在区间
上函数
连续且恒有
,那么定积分
表示由直线
和曲线
所围成的曲边梯形的面积.知识卡片2:一般地;如果
是区间
上的连续函数,并且
,那么
.这个结论叫做微积分基本定理,又叫做牛顿-莱布尼茨公式.
(1)用定积分表示曲线
及
所围成的图形的面积,并确定
取何值时,使所围图形的面积最小;
(2)一列火车在平直的铁轨上行驶,由于遇到紧急情况,火车以速度
(单位:
)紧急刹车至停止.求:
①求火车在刹车4秒时速度的瞬时变化率(即4秒时的瞬时加速度);
②紧急刹车后至停止火车运行的路程.
