六年级上册的语文的第一篇课文是什么? 物理选择题,求解 一道大一的数学分析题?a1=1,a2=2 ,an=an-1+an-2 ,证明：∑1/an 收敛. 已知：f'(x)=c-f(x),求证：f(x)=c-c*e^(-x).希望写的易懂一些，俺的数学不太好~ 大一数学分析题,1.设{an}是无穷小数列,{bn{是有界数列,证明{anbn}为无穷小数列2.若{xn}中有一个子列趋近于a,又{xn}中任一子列皆收敛,能否断定{xn}的极限等于a?请证明.希望能详细点. 大一数学分析题fx在x0右邻域内连续且在右邻域可导,其导函数从右趋于x0的极限存在,则这个极限等于x0这点的右导数第二题,用泰勒展开求arctgx在零处的n阶导数　　　　紧急呀, 氢氧化铜固体受热分解能得到两种产物,其中一种为固体.某兴趣小组为确定这种固体产物,氢氧化铜固体受热分解能得到两种产物,其中一种为固体.某兴趣小组为确定这种固体产物,进行如下实 松柏应该怎么形容? 一道数学分析题+∞ mπ第一步,为什么 ∫.= lim ∫.成立0 m—>+∞ 0 一道数学分析题,设r²=2a²cos2θ在θ=6/π处,求dy/dx 一道数学分析题, 按x的正整数幂,写出函数的展开式至含有指定阶数的项（带皮亚诺余项）（1）arctanx到含x^4 的项（2）tanx到含x^4 的项 一道数学分析题,求助,谢谢!设f(x)=∫ (1→x) lnt/(1+t) dt ,其中x>0,则f(x)+f(1/x)=______. 描写松柏的拟人的4字词语 I dont care ,I am OK Please try to adapt to the life like this ,and you Will find that the man whI dont care ,I am OK Please try to adapt to the life like this ,and you Will find that the man which is the hero in your eyes is not the all of your life Men will (wipe out) all the natural resources if they continue consuming like that.这里的wipe Like a person will hope that man's happiness is oneself 5年级下数学笔算题（分数加减,小数加减,分数乘除） 有争议的非谓语题目,求详解soon ,people hope ,the rains will return and ease the hardship the farmers .A facing B faced C faces D faced with 两题非谓语,求讲解.①She had a very（ ）when she heard the news.A.disappointed lookB.disappointing lookC.disappointed appearanceD.disappointment look这四项我都糊里糊涂的,求逐项分析.但我选B.我是这样理解的,look?不就 非谓语 要详解 续11 A computer does only what thinking people _____.A.have it do B.have it done C.have done it D.having it done 2 _____ your essay with his,yours was more instructive.A.Compared B.If to compareC.After I compared D.When comparing （1）已知X-Y=-3,XY=-4,求X③-Y③（2）已知a+b+c=0,a②+b②+c②=1,求ab+bc+ca的值（3）已知X+Y=5,X②+Y②=13,求代数式X③Y+2X②Y②+XY③的值（4）已知X②-X-1=0,求代数式-X③+2X②+2009的值*注：②/③：代表二 求人接几道数学题,因式分解4、（x²-y²)-(x+y)²-4(x-y)²5、已知x=二十二分之七十五,y=二十五分之四十四,求（x+y）²-（x-y)²的值6、已知a=747k+997,b=747k+998,c=747k+999,求多项式a²+ 用E=blv推导e=Emsinwt 四个不同的自然数的乘积是1989,四个数的和最大是多少啊? 还是英语非谓语求帮助,The country has already sent up three unmanned spacecraft ,the most recent __________at the end of last MarthA has been launchedB having been launchedC being launchedD to be launched为什么选B,我选的是A 感生电动势E=BLV,怎么来的? When I handed the report to John,he said that Geoge was the person___.A to send ,B.for sending it,C.to send it to ,D.for sending it to是哪一个？必有重赏 电动势E=BLV中V的具体含义 Seen on top of the mountain,the city looks more beautiful.这句话里"Seen"可以被理解成这城市在山上"被看",所以用Seen而不是seeing吧很多句子和单词都这样..但是遇到了两个题:Considering his age,the little boy read q 请问E=BLv是代表瞬时电动势吗? 求这套卷子所以题目的答案
