sat2 开闭区间问题If the range of a function is (–5,5),this means that –5 is included in the range,but 5 is not.(The range is said to be “inclusive” of –5 but exclusive of 5.) 请解释这句话为什么是这样啊...这不是开区

sat2 开闭区间问题If the range of a function is (–5,5),this means that –5 is included in the range,but 5 is not.(The range is said to be “inclusive” of –5 but exclusive of 5.) 请解释这句话为什么是这样啊...这不是开区 sat2 数学：if o SAT2数学矩阵问题 单调区间的开闭有区别吗? 那个减区间 开闭是不是都可以 概率 连续性分布中的概率密度的开闭区间问题比如一个 连续分布的概率密度f(x) 如下：f(x)=x+5 b SAT2 Sat2 开闭区间是初中学的还是高中学的? SAT2巴朗物理 P61最下方说how far the object has fallen when it is 10 meters away from the base,if the horizonal velocity is 10 meters per second.The answer is -4.9.很奇怪为什么这里的4.9要加负号?问题中不是说how far has fallen sat2问题为什么NaOH是conjugate acid? SAT2一道物理题..The volume of a given mass of gas will be doubled at atmospheric pressure if the temperature of the gas is changed from 150 to .. 微积分的连续的问题……闭区间上有定义,开区间上连续……为什么要强调开闭区间?若函数在闭区间[a,b]上有定义,在开区间(a,b)内每点都连续,且在a右连续,在b左连续,则称函数在闭区间[a,b]上 一道急需解决的SAT2 Math问题The set of odd intergers is closed under?正答：multiplication sat2 if 10 coins are to be flipped and the first 5 all come up heads,what is the probability that exactly 3 more heads will be flipped? 2次函数与区间的开闭问题f(x)=x^2+a/x,x不等于0,a属于r,若函数在x属于【2,正无穷）上为增函数,求a的取值范围 区间的开闭问题如题要使得f(x)在【2,正无穷）上为增函数已知f'(x)=（2x^3-a）/x^2,求a的取值范围 高数连续与可导问题在中值定理那章里面 几个定理都会有f(x)在开区间（A,B）可导 在闭区间[A,B]连续 的前提 这里的开闭区间是怎么定义出来的啊?换做是在闭区间内可导
