解题方法
4 . 我国南北朝时期的数学家祖冲之(公元429年-500年)计算出圆周率的精确度记录在世界保持了千年之久,德国数学家鲁道夫(公元1540年-1610年)用一生精力计算出了圆周率的35位小数,随着科技的进步,一些常数的精确度不断被刷新.例如:我们很容易能利用计算器得出函数
的零点
的近似值,为了实际应用,本题中取
的值为-0.57.哈三中毕业生创办的仓储型物流公司建造了占地面积足够大的仓库,内部建造了一条智能运货总干线
,其在已经建立的直角坐标系中的函数解析式为
,其在
处的切线为
,现计划再建一条总干线
,其中m为待定的常数.
注明:本题中计算的最终结果均用数字表示.
(1)求出
的直线方程,并且证明:在直角坐标系中,智能运货总干线
上的点不在直线
的上方;
(2)在直角坐标系中,设直线
,计划将仓库中直线
与
之间的部分设为隔离区,两条运货总干线
、
分别在各自的区域内,即曲线
上的点不能越过直线
,求实数m的取值范围.
