定理4(介值定理) 设函数f(x)在闭区间[a,b]上连续,且f(a)(b),那么,对于 f(a)与f(b)之间的任意一个数C,在开区间(a,b)内至少有一点5 使得=C

Legal History for a Dummy: A Comment on the Role of History in Judicial Interpretation of the Confrontation Clause by Peter Tillers* I struggled quite a bit over what I should talk about today. I know a little bit about exploratory fact investigation1 and about related matters such as induction and what philosophers of science call the logic of discovery.2 I thought about discussing the worrisome implications of Crawford v. Washington3

线性方程组 基本概念题 例1设齐次线性方程组A5x3X=0仅有零解,求r(A) 解方程组中未知量个数n=3,又方程组AX=0有惟一零解,所以r(A)=n,故r(A)=3

Ⅰ、选择题(共10小题,每小题3分,共30分) 每题给出四个答案,其中只有一个是正确的,请将正确答案的标号(A或B或C或D) 写在题号前的横线上 1、积分∫es(-3)d等于 (A)0(B)1(C)e3OD)e3 2、下列等式不成立的是 (A)f0)6\(0)=f(0)6'(0 B)A06(0=f()5( (C)f)*6(0)=f(0 (D)f0)°(0)=f(0

6.1定积分与不定积分 给定非负函数y=f(x),定义于闭区间[a,b],如果我们要求函数图形y=f(x)下边 曲边梯形面积,就需要定积分[f(x)dtx。 定闭区间[a,b]内任意时刻的即时速度y=∫(1),求[a,b]内走过路程,也需要定 积分O)d 定义函数f(x)定义在[a,b上

2.1序列极限定义 定义域为N的函数也称为序列,记为f(),f(2),A,f(n),A,习惯上记为 x1,x2,A,xn,A,或简单地记为{xn}。其中xn称为通项,它可由公式给出,也可由其它法 则给出

Recursion-breaking an object down into smaller objects of the same typeis a ma- jor theme in mathematics and computer science. For example, in an induction proof we establish the truth of a statement()from the truth of the statement P(n-1). In pro- gramming, a recursive algorithm solves a problem by applying itself to smaller instances
