这个方程可看作X关于y的函数(x是y的函数),关于x的一阶线性非齐次微分方程,可利用公式(在课本上给y是x的函数的公式为y=e^-∫P(x)dx(∫Q(x)e^∫P(x)dx+C))

有区别.你说的“f(x)在x趋近于a的空心领域里有界”中f(x)有界的前提为x趋近于a的空心领域里,若x不趋于a,则f(x)未必有界,这点可用函数极限的局部有界性定理来解释,可用语言序数为某一有极限函数f(x)仅在一个小范围内(...

(Ⅰ)依茎叶图判断哪个班的平均分高?
(Ⅱ)现从甲班高等数学成绩不得低于80分的同学中随机抽取两名同学,求成绩为86分的同学至少有一个被抽中的概率;
(Ⅲ)学校规定:成绩不低于85分的为优秀,请填写下面的2×2列联表,并判断“能否在犯错误的概率不超过0.025的前提下认为成绩优秀与教学方式有关?”

(Ⅰ)甲班高等数学成绩集中于60分-90分之间,而乙班数学成绩集中于80-100分之间,
所以乙班的平均分高.-----(3分)
(Ⅱ)记成绩为86分的同学为A,B其他不低于80分的同学为 C、D、E、F,
“从甲班高等数学成绩不得低于80分的同学中随机抽取两名同学”的一切可能结果组成的基本事件有:
(A,B)、(A,C)、(A,D)、(A,E)、(A,F)、(B,C)、(B,D)、(B,E)、(B,F)、
(C,D)、(C,E)、(C,F)、(D,E)、(D,F)、(E,F),一共15个,
“抽到至少有一个86分的同学”所组成的基本事件有:
(A,B)、(A,C)、(A,D)、(A,E)、(A,F)、(B,C)、(B,D)、(B,E)、(B,F)
共9个,------(5分)
故 所求事件的概率为 P=[9/15]=[3/5].-----(7分)

甲班 乙班 合计
优秀 3 10 13
不优秀 17 10 27
合计 20 20 40---------(9分)
(Ⅲ)K2=
4×(3×10×−10×17)2
13×27×20×20≈5.584>5.024,因此在犯错误的概率不超过0.025的前提下,
可以认为成绩优秀与教学方式有关.------(12分)

一个强调塑,一个强调透,本来就不是一回事,学哪个以后都要从新学另外一个,水彩上手难但是以后却容易,水分相反.建筑学这样的工科学生主要通过材料了解空间表达,色彩认识,达到对目标物的迅速,准确和到位,开课目的不是学艺术,如果是美术系的,教学深度等等都会是另外一回事.我认为学生画水粉常常会很厚,如果这样还不如学习水彩.习惯厚的表达,学习水彩非但不会容易反而会很有障碍.也有学生把水彩画厚当水粉用,说不定他们以后学水粉会容易.总之,这东西学一样不就得了,如果要继续还不如学学其他的表达方法,比如丙稀什么的.

Every day we learn in the classroom, one will be able to see the rise of "hard-compliance, respecting teachers, the school loved" the school motto. However, whether or not we thought of ourselves in the end there is not really to "respect for the teaching profession," This is it? ?
Against teachers, it is easy to think of Confucius, the blind writer Helen Keller, etc., they can be called Jesus Christ, name and good willcoexistence, go down in history. And tens of thousands who work in the spirit of open country on the teachers, only because they do not have a celebrity or a great man as the magnificent achievements of their efforts and not known by the conviction on the praise. They work hard, and in the hot sun, in heavy rain, the yield of fruit are also sweet fruit acid fruit, when the community in enjoying the fruits of them, please remember them! ?
The glorious work of the great teachers, has been affirmed and accepted by people. "Village of female teachers," "Spring," "love education" and "last lesson" in the image of teachers has been etched into the hearts of people. However, the aesthetic perspective of a difference there: in a certain distance apart are better things from a closer, it is the one thing. Hence, many people are willing to engage in the profession, does not include teachers. Actually, the flowers and the gardener is zhulianbihe, solidarity, but as a result of teachers and students meet every day, a short distance, and many students of teachers not "to love each other." We are in the habit of "shibiao" standards of teachers, and teachers if not expected, as there are imaginative power, some people will be surprised and even ridicule. I think that teachers are not Superman, but also by no means inferior. As a result of the work of the teachers are real people, not drawings or machine tool life, therefore, teachers have their special work stand, I am afraid not very well understood. ?
Rostrum, the eyes of a teacher's Temple, no longer rostrum than the deprivation of the rights of teachers but also feeling sad and a shame. I am the teacher, but also will not easily give up the podium. Sick leave揣着single rostrum, not advanced in school stories, such a thing as too much. The reasons why, as a female teacher said, real simple: "I am playing a sweater, do not want to let others to play a few half-way into the needle, because everyone is different elastic gesture." This is the case, 365 a year days, regardless of heat or ice cool winter day, the thought of waiting for the class of five looking for a dozen students, teachers will always try to remove all obstacles. A rostrum, he must forget all the pain of all this, the only student in his mind at the moment. Their precious youth to dedicate the podium, in the re-diploma today, they do not have the energy nor time to enjoy the book and then group earned higher diploma, teacher's own ability and experience, the kind of professionalism more than Diploma no life! ?
Let us cherish this wonderful time and treasure to get along with teachers every day.

What does friendship mean? There is no definite answer. An eternal theme in literature, friendship is also indispensable in daily life. Friendship is to our life what salt is to dasher. When you are happy, friendship is just like adding flowers on the brocade; when you are sad, friendship is a dose of consolation; if you are in trouble, friends will surround you and remove the barriers for you; if you have a hard nut to crack, you can turn to friends for help. We admire the great friendship between Marx and Engel, which firmly combined them and pushed them forward on the road to exploring and fulfilling Communism.Friendship isn't almighty, but no one can live happily withoutit.

楼主很仔细,确实发现了在计算无穷大减无穷大时的细微差别,
提供了堵住那些胡乱叫嚣的等价无穷大代换的人嘴的实例.


下面的两张图片解释,第一张是按照普普通通计算无穷大减无穷大型
不定式的方法,其中采用了波罗的海,跟罗毕达求导法则.


第二张挂图,分析、追究了从-1,变成+1的来源.



甲对乙说:“我如今比你大10岁”乙对甲说:“4年前你的年龄比我大一陪”现在两人各几岁?

甲对乙说:“我如今比你大10岁”
那么甲4年前也比乙大10岁
设甲如今x岁
x-4=(x-10-4)*2
解得
x=24
所以甲现在24岁
乙14岁
大一.第二题.
大一.第二题.

Beloved teacher,dear partners :
Hello everyone!I called # # #,the first time today I stand on the rostrum speech,and speech is the first election monitor,at this time I am excited,but also very nervous.It is a squad many students looking for jobs,the need for a capable and caring people to play,I believe I have the ability.I-12 has been a leader,we are not continue to give me this opportunity?Let me childhood diary for the whole class to stay in the unparalleled service fond memories!I warm and cheerful,loving the collective unity of the students,with love.I despise the disadvantage of poor students,not like other people's advice to me in the days to come,I will remove these defects.
If I win the election on the head when,I will use the exuberant energy,a clear mind to do this work,I will organize a series of activities such as reading,speech,etc.,and of course I do not many more.I think we should have it as a doer,not those beautiful words to describe.If I had lost that I still have many shortcomings,I will continue to self-improvement.
Tempering my work,I created a living.Dell Carnegie said,"should not be afraid of selling their own,as long as you believe that you have the talent,you should consider themselves eligible for promotion was this or that job."
Students,and trust me,support me,please vote for me,thank you!

敬爱的老师、亲爱的伙伴:
大家好!我叫###,今天我第一次站在讲台上演讲,而第一次演讲就是竞选班长,此时此刻我很激动,也很紧张.班长是一个许多同学向往的职位,需要一个有能力有爱心的人来担当,我相信我有这个能力.我在一二年级都当过班长,大家是不是继续给我这个机会呢?让我童年的日记里留下为全班同学服务的无比美好的回忆吧!我热情开朗、热爱集体、团结同学、拥有爱心.我的缺点是看不起差生,不爱听别人对我的劝告,在未来的日子里,我将改掉这些毛病.
假如我竞选成功当上班长,我将用旺盛的精力、清醒的头脑来做好这项工作,我将举办一系列活动如朗诵、演讲等等,当然还有很多我就不多说了.我想我们都应该当个实干家,不需要那些美丽的词汇来修饰.假如我落选了,说明我还有许多缺点,我将继续自我完善.
工作锻炼了我,生活造就了我.戴尔卡耐基说过“不要怕推销自己,只要你认为自己有才华,你就应该认为自己有资格提任这个或那个职务”.
同学们,信任我、支持我,请投我一票,
###
保证对的..!

大一新生求助高数题_勒让德多项式
勒让德多项式Pn(x)由公式[(x^2-1)^n](n)=Pn(x) (n阶导数)确定
证明等式:
Pn+1(x)-(4n+2)xPn(x)+4n^2Pn-1(x)=0
用递归法(可我不会做),小弟在此谢过了!

首先这个题目就是个错题,不知道是不是你打错了...
取n=1时,
P2(x)-6P1(x)+4P0(x)
=12x^2-4-12x+4
=12(x^2-x)≠0
结论不成立哦.

5、不知道△p是什么,我猜是溶液上方水蒸气分压,那么请考虑引入的微粒数,显然尿素是最少的;
6、关键的地方看不到,到底做不做非体积功?我猜是不做;
15、只要定性考虑c和Kb的影响即可...铵根浓度大了水解平恒终态的H+不也大么...即c越大,酸性越强,然后Kb是描述碱性的,越大碱性越强,酸性越弱,pH与之正相关,注意这里是pKb...所以他还是-号...
16、我不明白你为什么算错...pOH=-lgKb(后面一截是0不用解释了吧...)=4.744,14一减即得9.255
18、简单计算一下就可以知道OH-的浓度是3.8*10^7,OH-比H+多,你说酸性还是碱性?
22、你可能缺少一个常识性的条件,浓度为多少可以认为沉淀完全?我们这边用的是10^6mol/L;
23、又有一个数看不到...我猜是1好吧..不知道你们老师是怎么教的,反正我高中老师是教我算被称为浓度商Q的一个玩意(就是像算K一样各种浓度相乘除),然后和K比较,就可以判断方向了,这一题你要把它的方程式看成两个子式的叠加就好理解了,方程式叠加K怎么算我就懒得说了.
24、ACD我知道有,B的话还真没见过,如果非要给理由我会说他的配体太多了,一个en就可以提供很多;
26、Kf*[M2+][X-]^4=[MX4]2-;
28和29完全是一回事...我想你可能比较不理解那个转移电子数n,注意,在计算过程中他们恰好被H+前面的系数次方消掉了.
