cost-cos³t
___ the cost,the dress doesn’t suit me.a

Apartfrom,且不说,撇开,暂不提.Exceptfor要不是由于,除了...之外.具体辨析词组意思,还是C比较符合语意.

The house is worth--- because it dosen't cost much.

因为worth没有被动语态的形式.worthdoingsth:值得做某事;

电路习题全解?二端网络的电压电流分别为:u(t)=10cost,i(t)=5cos(t+60),则平均功率为多少?

The car__much money.A isn't cost B didn't cost选哪个怎么解释

Bcost是动词,要用助动词be动词不可以直接跟动词连用

求解不定积分∫[t*e^(-cost)]dt

它的不定积分不是初等函数,不能用具体式子表示!

Apart from the cost, the dress doesn't suit me

apartfrom表示除了...之外的意思,而exceptfor表示美中不足,inadditionto有补充说明的含义.这些你可以在见到的例句中理解,不要太较真,因为我们汉语中也有不好说明的词啊,只有

Constant cost production possibility curves 跟 Increasing cos

Constantcostproductionpossibilitycurves是一条直线.至于Increasingcostproductionpossibilitycurves就是一条弧线.这个不知道

一道积分题求助(t-sint)√(1-cost) dt

点击[http://pinyin.cn/1aSld8B6HG2]查看这张图片.[访问验证码是:924505请妥善保管]能看见么?不能看见告诉我~再答:

the house cost that we didn't it

这里的money是不可数名词再问:money肯定是不可数名词呀,所以,这俩前面都加了much再答:such+adj+不可数名词+that…hehasmadesuchgreatprogressthatt

that shouldn't _long.A:cost B:take

B.cost一般用于钱的方面.

若t是第三象限的角,那么sin(cost)除以cos(sint)的值是大于零还是小于零?

若t是第三象限的角,t∈(π+2kπ,3π/2+2kπ),k∈Zcost∈(-1,0),sin(cost)<0sint∈(-1,0),cos(sint)>0sin(cost)/cos(sint)<0

The holiday shouldn't cost very much.

度假不该花太多钱!

matlab 中如何根据这个函数 tanx=(2(cost-cos(pi/4)*sin(t)) /(2(cost-cos

t=-pi/2:0.01:pi/2;x=atan((2*(cos(t)-cos(pi/4)*sin(t)))./(2*(cos(t)-cos(pi/4)).*cos(t)+1));plot(t,x)

将参数方程化为普通方程 1.x=4+3t y=2+t 2.x=cos^2 y=sint 3.x=a/cost y=b*t

1.x=4+3ty=2+t3y=6+3t相减x-3y=-2x-3y+2=02.x=cos^2ty=sint平方,相加x+y^2=13.x=a/costcost=a/xy=b*tanty*coxt=b*

it doesn't cost as

它花费不多

He didn't want to tell me how much the bag____. A cost B cos

答案:Acost的过去式就是cost本身.

向量a=(cosp,sinp),b=(cost,sint),la-bl=13分之4根号13,(1)cos(p-t)的值

la-bl^2=4/13=a^2+b^2+2|a|*|b|*cosθθ为向量a,b的夹角,即θ=|p-t|,cosθ=cos(p-t);cosθ=(4/13-2)/2=-11/13
