I don't like A and B 和 I don't like A or B 有什么区别?I don't like A and B 和 I don't like A or B 有什么区别?打酱油的别回复. 英语

——Tom,you are 10 minutes late,please don't be late again next time.——_________.A.Yes,I won't.B.OK,I will C.Yes,I will请问这道题应该选哪一个,为什么?不英语

意思，选项打错了，应该是 A

1.Cou you tell me at the meeting? Sorry,I don't know.I didn't go to the meeting that day.1.Cou you tell me at the meeting? Sorry, 英语

don't know.I

Complete the sentences using your own ideas.1.If I get up late tomorrow,2.If I don't finish my homework,3.If I eat 英语

too much lunch

i don't want to eat anything.i'm feeling well today.().i hope you'll be better Ait doesen't matterA.it doesen't matter B .i'm sorry to 英语

hear that C .d

e^(2πi(1/6))=(e^2πi)^(1/6)=1^(1/6)=1e^(2πi(1/6))=e^(πi/3)没弄明白,希望将此解释清楚,我的意思是，同一个数e^(2πi*(1/6))有两个结果：一个是1（实数），一个是e^(πi/3)（非实数的复数），它们到语文

底该取哪一个？（你们说的我都

已知函数y=(e^x-a)^2+(e^(-x)-a)^2(a属于R,a不等于0),求y的最小值Y=(e^x-a)^2+(e^(-x)-a)^2=(e^x)^2-2ae^x+a^2+(e^(-x))^2-2ae^(-x)+a^2=(e^x+e^(-x))^2-2a(e^ 数学

e^ (-x)) ^2-2

用matlab求最大值i=(18-t^(2/3))-(5+t+2t^(2/3))i是因变量,t是自变量.这个函数是减号，式子没化简，化简完是i=13-3t^(2/3)-t 其他

f(x)=e^x+∫tf(t)dt-x∫f(t)dt解f'(x)=e^x+xf(x)-∫f(t)dt-xf(x)=e^x-∫f(t)dtf''(x)=e^x-f(x)得f''(x)+f(x)=e^x因此通解为C1cosx+C2sinx特解设为Ae^x,解得A=1/2于数学

2sinx特解设为 Ae^x

复数和三角函数问题sin(ix+t)能不能表示成不含i的形式?其中i是虚数单位我本来的想法是先展开成sin(ix)cos(t)+cos(ix)*sin(t)然后对其中含有i的两个三角函数用泰勒展开最后对数列求极限但是，数学

壳了
