She went to Bristol yesterday(用where针对Bristol提问) where did she went yesterday? She went to the countryside( ).A.in the morning at nine on June first,1968 B.on June first,1968 in the morning at nine C.at nine in the morning on June first,1968 D.on June first,1968 at nine in the morning could you please ________ the picture on the wall?a pick up b look up c get uo d put up 如果(cosα)^2-(cosβ)^2=a,则sin(α+β)sin(α-β)=?我的步骤是:(cosα)^2-(cosβ)^2=a(cosα-cosβ)(cosα+cosβ)=a【因式分解了】(2· cosα+β/2 · cosα-β/2)(-2· sinα+β/2 ·sin α-β/2)=a【和差化积】然后后面 如果sin(π/2+α)=cosα,sin (π/2-α)=cosα,那么sin(π/2+α)=sin(π/2-α)对吗? sin(2π-a)cos(π/2-a)/cos(π-a)sin(π/2+a)化简…再求值(要有大概过程) The l___of the songs are very beautiful and sound like a poemPlaying is an art that is played by pulling piying By s ___His grandpa died of h_______disease last year Do you like Cai Yilin's songs?Yes ,they_____really beautiful .A look B listen Csound为什么不是listen? do you like Jay Chou's songs?Yes,they()raelly beautiful.A.lookB.listenC.soundD.see Do you like the song You and Me -of course.It ( )really beautiful.A:listens B:thinks C:hears D:sounds 有依次排列的三个数:275,对相邻的两个数都用右边的数减去左边的数,所得的差写在这两个数的中间,可以得到一个新的数串:2、5、7、-2、5,把这个过程称为第一次操作:如果这样继续操作下 1.(1-2^2分之1)×(1-3^2分之一)×.×(1-10^2分之一)=?2.(5分之3)^15÷(-3分之5)^14=? -2³÷(-4)³+1÷(-2分之1)³12-(9分之7-6分之5)乘以4²(-3)²×(-2)-{(-2)×(-1)}²我都做了, 1.在於铁路平行的一条公路上,有一行人与骑车人同时向南行进,行人的速度是1米/秒,骑车人的速度是3米/秒.如果一列过车从他们背后开来,它通过行人的时间是22秒,通过汽车人的时间是26秒,那 get your feet under the table The dictionary and the baseball_____under the table.填空 已知函数f(x)=-x^2+2x,g(x)=kx,定义域都是[0,2],若|f(x)+g(x)| 如图所示电路,R1=R2=4 Ω,R3=R4=2 Ω,UAB=6 V,求:(1)电流表A1和A如图所示电路,R1=R2=4 Ω,R3=R4=2 Ω,UAB=6 V,求: (1)电流表A1和A2的示数(不计电流表的内阻).(2)R1与R4两端电压之比. sin(a-b)sin(b-r)-cos(a-b)cos(r-b) sin(α-β)sin(β-r)-cos(α-β)cos(r-β) 1.sin(α-β)sin(β-r)-cos(α-β)cos(r-β)2.( tan4分之5π+tan12分之5π)/(1-tan12分之5π)3.[ sin(α+β)-2sinαcosβ]/2sinαsinβ+cos(α+β) 存在α,β属于R,使cos(α+β)=cosα+sinβ是假命题吗 sin(α+β)cos(r-β)-cos(β+a)sin(β-r) 化简 什么情况下需要进行二次检索?二次检索时,主要运用的检索技术有哪些,应用这些技术可以达到什么样的效果 常用的文献检索的方法是什么,在实际中如何应用? 已知定义域为(0,+∞)的函数f(x)满足:对任意x∈(0,+∞),恒有f(2x)=2f(x)成立;当x∈(1,2]时,f(x)=2-x,若X1 和X2是方程f(x)=a(0<a≤1)的两个实数根,则X1-X2不可能是A24 B72 C96 D120 with-department stor-went-the-to-Danny-I(连词成句,请注意标点) they went to the department store yesterday.改为否定句—— ——they——yesterday快快,填空 当α是第一象限角时,sinα=根号[(1-cosα)/2],这句话为什么是错的? 月考(六),英语 改错One morning Mrs.Jenkins went to department store 56to buy a coat.There was not shop assistant in theand wanted to buy a coat,too.云南师大附中2011届高考适应性月考卷(六)3月25日15:00~16:40 cos(A-B/2)=-1/9,sin(A/2-B)=2/3,A是第二象限角,B是第一象限角,cos(A+B)=?ji! α是第一象限角cosα√(1-sinα/2)/(1+sinα/2)+cosα√(1+sinα/2)/(1-sinα/2) 检索式是什么
