Exercises1. Copy the statements of five definitions and five theorems from one of your math textbooks. Identify the use of the defined words in the statements of the theorems. Give examples that illustrate the theorems. Show how the conclusions of the theorems don’t necessarily hold if the hypotheses are not satisfied. Definition1 (definition2.1)Let X be a vector space over F .A norm on X is a function .:X →R such that forall x,y ,∈X and α∈F, (1)0≥x ;(2)0=x if and only if x=0,(3)xx αα=,(4)yx y x +≤+.EXAMPLE1The function.:F n→R defined by212121)(),...,,(∑==nj j n x x x x is a norm on nF .(1)212121)(),...,,(∑==nj j n x x x x ≥0(2)212121)(),...,,(∑==nj j n x x x x =0⇔0=⇔=X x j(3)2121212121)()(),...,,(∑∑====nj j nj j n x a ax x x x a(4)21212121212121212121)()()()(),...,,(),...,,(∑∑∑∑====+≤+=+nj j nj j nj j nj j j n n y x x y x y y y x x xIt is a norm.Definition2 (definition 3.3)Let X be a complex vector space .an inner product on X is a function (., .):C X X →⨯suchthat for all x,y,z ∈X,C ∈βα,, (1) (x,x)∈R,and (x,x)≥0; (2) (x,x)=0 if and only if x=0; (3) ),(),(),(z y z x z y x βαβα+=+ (4) ),(),(x y y x = ExampleIf )(,2X L g f ∈ and the function (.,.):F X L X L →⨯)()(22defined by⎰=Xd g f g f μ),(is an inner product on )(2X L . This inner product will be called the standard inner product on)(2X L .ProofLet)(,2X L g f ∈. Then by holder's inequality ,with p=q=2 (theorem 1.55)and the definition of )(2X L ,∞<≤⎰⎰⎰212212)()(μμμd g d f d g f X X X ,so)(1X L g f ∈ (a)0),(2≥=⎰μd f f f X(b)00),(2=⇔=⇔⎰f d f f f Xμ(c)),(),(),(h g h f h g h f d h g f h g f XXXβαβαμβαβα+=+=+=+⎰⎰⎰(d)),(),(f g d f g d g f g f X X ===⎰⎰μμ so it is an inner productDefinition 3 ( definition 3.26)Let X be an inner product space and let A be a subset of X . The orthogonal complement of Ais the set(){}0,:=∈=⊥a x X x A for all A a ∈. Example (exercise 3.15)If{}{}0:22=∈=n n x l x A for all N n ∈,find ⊥A . Solution :Let (){}0:122=∈=-n n x l x S for all N n ∈.if S x ∈and A y ∈ then 0),(1==∑∞=nn n y x y x , thus ⊥∈A x , and so ⊥⊂A S .Conversely, let ⊥∈A x suppose 012≠-m x for some N m ∈. The vector 12-m e in the standardorthonormal basis in 2l belongs to A ,so()1212,--=m m xe x , which is a contradiction . Thus012=-m x for all N m ∈, so S x ∈ .hence S A ⊂⊥. And so S A =⊥Definition 4 ( definition 4.16)let X and Y be normed linear spaces and let ),(Y X B T ∈. The norm of T is defined by{}1:)(sup ≤=x x T T .Example (example 4.18)If []F C T F →1,0: is the bounded linear operator defined by T(f)=f(0).then 1=TSolution :Becauseff T ≤)( for all []1,0F C f ∈,hence{}xk x T k T ≤=)(:inf1≤for allX x ∈.

Examine the proofs of three or four mathematical theorems. What is the structure of these proofs? Identify where the hypotheses of the theorems are used in the proofs.Theorem2.25(Riesz' Lemmma )Suppose that X is a normed vector space ,Y is a closed linear subspace of X suchthat X Y ≠and ɑ is a real number such that 0<ɑ<1. Then there exists X x ∈αsuch that1=αx andα<-z x for all y ∈Y.ProofFirst , begin with the hypotheses of Y is a closed linear subspace of X such that X Y ≠. We have{}0:inf >∈-=Y z z x d ,where x ∈X/Y by part (d) of theorem 1.25((){}0:,inf =∈⇔∈A y y x d A x ) With the hypotheses of 0<ɑ<1, 1-<αd d , so that there exists Y z ∈ such that1-<-αd z x .Next ,we should make 1=αx ,so letzx z x x --=α.then1=αxLast ,we showα<-z xααα=>-+--=------=---=--d d y z x z x zx z x y z x z x z z x x y z x z x y x )()(11It is proved .Theorem 3.34Let Y be a closed linear subspace of a Hilbert space H. For any x ∈H, there existsa unique y ∈Y and z ∈⊥y such that x=y+z, Also ,222z y x +=.ProofWe can remember the former theorem 3.32:let A be a non-empty ,closed, convex subset of a Hilbert space H and let p ∈H, then there exists a unique q ∈A such that{}A a a p q p ∈-=-:inf so we can guess q is the unique y .First , Y be a closed linear subspace of a Hilbert space H. It follows theorem 3.32 that there exists a unique y ∈Y , such that for all u ∈Y,ux y x -≤-.Next ,according to the theorem ,it needs to find z, x=y+z.so we let z=x-y.we only need to show z ∈⊥y .According to Lemma 3.30 let Y be a linear subspace of an inner product space X,thenYy x y x Y x ∈∀≥-⇔∈⊥..⊥∈=-≥+-=-Y z z y x u y x u z ,)(.we proof the existence.Then ,we show the uniqueness.

exercise是可数还是不可数

exercise既是可数名词，同时也是不可数名词。

1.exercise泛指“锻炼”时，做不可数名词，如：take exercise锻炼身体、take more exercise多锻炼；2.exercise表示“体操”或“练习（题）”时是可数名词，要用复数形式。

如：do morning exercises （做早操），do eye exercises(做眼保健操)，do English exercises(做英语练习)。

1、名词“exercise”可以和in搭配，意思是“有特定目的活动或事情”，此处是可数名词。

比如：“an exercise in team work一个锻炼团队配合活动”。

用法：1、“Exercise”可以表示“一套特定的动作让身体变得更强壮和更健康”，此处的“exercise”是可数名词，通常在exercise之前会有另一个名词来说明是哪方面的运动。

例句：I am doing knee exercises to help my recovery from a knee operation.我正在做膝关节运动，帮助我做膝盖手术后的恢复。

2、“Exercise”作为名词时还可以表示“练习”，是可数名词，指“为了掌握某种技能而做的练习”。

例句：Try these online arithmetic exercises; they can improve students’ maths skills.试试这些网上算术练习，它们可以提高学生的数学技能。

3、复数形式“exercises”还会出现在军事话题中，意思是“操练”。

例：naval exercises海军操练4、“Exercise”还有一个相对比较正式的含义，意思是“使用，运用”，不可数名词。

例：the exercise of self-control自我控制力的运5、“Exercise”作为动词时的是“锻炼，运动”，指“为了身体健康而做运动”。

II. Cultural background May 1941, German bombers assaulted London in what turned out to be the final heavy mission of the Battle of Britain. More than 500 aircraft dropped highly explosive and incendiary bombs which resulted in many fires and caused more than 3,000 casualties. But the Battle of Britain was lost, and with it Germany’s chance of winning the war had gone. 26 July 1941, U.S. President Franklin D. Roosevelt ordered all Japanese assets frozen. He also ordered the suspension of all trade with Japan and laid an embargo on oil. All this gave rise to the attack on American naval forces at Pearl Harbor by Japanese on 7 Dece mber 1941.
