改正下列英語句子的錯誤
1.does she likes apples?
2.-do they like oranges?-yes,they like.
3.would you like any tea?
4.teacher's day is september tenth.
5.how many monthes are there in a year?


does she likes apples?
改正:Does she like apples?
(like是動詞,does後邊要用動詞原型)
2.-do they like oranges?-yes,they like.
改正:Do they like oranges?-yes,they do.
(這是一般疑問句式,一般疑問句的原則就是把do或does提到主語的前面,回答時要把主語提前)
3.would you like any tea?
改正:Would you like some tea?
(some和any的一般的用法是some用於肯定句中,any用於否定句或疑問句中.但some在表示請求,許可或建議時,some用否定句或疑問句中.)
4.teacher's day is september tenth.
改正:Teachers' day is september tenth.
(這是名詞所有格,這個要背,是特殊的.)
5.how many monthes are there in a yea?
改正:.How many months are there in a yea?
(因為是”month”月的意思,也是最特殊的複數形式.)



求下列函數的微分y=Inx/x和y=x^3(2x-1)^10


y=Inx/x,
dy=d(lnx)/x+lnx*d(1/x)
=(1/x^2-lnx/x^2)dx.
y=x^3(2x-1)^10
dy=d(x^3)*(2x-1)^10+x^3*d[(2x-1)^10]
=[3x^2*(2x-1)^10+20x^3*(2x-1)^9]dx.



一塊長方形的地,周長是240米,長是寬的三分之五倍,求菜地面積.


長方形地的長與寬之和=240/2=120米
長方形地的寬
=120/(5/3+1)
=120/(8/3)
=45米
長方形的長=45*(5/3)=75米
菜地的面積
=75*45
=3375平方米

設a>0且a不等於1,求證方程a^x+a^-x=2a的根不在區間[-1,1]內


(反證,分類討論)
不妨假設a>1.
1)若x=0,則2=2a,a=1,與題意不符,所以x不等於0.
2)若x在(0,1],則a^x在(1,a];a^-x在[1/a,1)
於是a^x+a^-x在(1+(1/a),1+a)的開區間內.
因為a>1,隨意a+a>1+a,即2a>1+a,方程等式不成立,所以x不可能在(0,1]區間.
3)若x在[-1,0),同理.
若0



古詩形容心事或者鬱悶的事怎麼用詞?直接用心事嗎

一個圓錐的體積是12立方分米,高是三分米,這個圓錐的底面積是多少平方分米


根據圓錐的體積公式:v=1/3sh,s=v÷1/3÷h,
12÷1/3÷3,
=12×3÷3,
=12(平方分米)
答:底面積是12平方分米.



小學的運算符號
a.b.c=12


是,因為乘法可以用“·”表示的.也就是說a·b·c=12
