1.令Q是有理数域,R是一个环,而f,g都是Q到R的环同构,且对任意整数n有f(n)=g(n),证明f=g2.证明,若f(x)互素,并且f(x),g(x)次数都大于零,那么可以选取u(x),v(x),使偏导(u(x)) 3(x+2)+66-(2x+2)=18的详解过程---各位--简单吧--所以快点哦--在线等---先回答的先采纳 关于社会作文的开头 有关道德的作文开头与结尾 初三 圆的 填空题第一题和第三题 已知y=(根号下3-X)+(根号下X-3)+5 ,求X÷Y的值 y=e∧xsinx,求y∧(4) 若x+1/2 y=e^xsinx怎么导 y=e^xsinx,则函数在点(4,y(4))的切线的倾斜角为钝角,锐角,直角还是0要原因 不是说倾斜角的范围是零到一百八十度吗,那为什么这题问的倾斜角可以大于180呢? 为什么直线的倾斜角范围不能等于180°?RT为什么不能重合? 已知函数g(X)=(x*x-4x+3) (x.-1) ,qiu g(x)的最小值忙中出错了,题应为“已知函数g(X)=(x*x-4x+3)/(x+1) ,(x>-1),求g(x)的最小值 (x+5)(3-2x)>=6 解题过程 6(x-3)=2x怎么解 还有 过程中的18怎么出来的 3.14*2x=2(x+6. 已知函数f x=lg(根号下4x方+b+2x)其中b为常数(1)若y=f(x)为奇函数,求b的值(2)求证y=f(x)的图像上不存在两点A.B,使得直线AB 平行于x轴 已知f(x)=e^xsinx,求y求y 1÷2x=1 x=1还是x=2 若函数f(x)=Asin(2x+b)(A>0),且对任意的实数,满足f(π/12+x)=f(π/12-x),求f(π/3) 函数y=根号下lg(4x-3)的定义域为?不然我会看不懂的 关于x的方程|x^2-2x-3|=a有且只有两个实数根,则实数a的取值范围为? 4个很简单的动词时态填空.急..Most cases of this kind of illness can ______(cure).When and where ________ the ORBIS ______ (set) up?You're wise and are often ______ (success).You ______ (have) a meeting next Friday,aren't you? 初三的英语时态填空.急用.A man was sitting at his doctor’s.He was telling the doctor about his problem.“I like football,you know,Doctor,” he said.“And my wife ________(be) hard to me since I became interested.She often ________(hear 用适当的时态填空1.She's __________ (live) here ever since she was ten2.Both of them ________(be)in Hongkong for ten days3.Both of them _______(come)to Hongkong ten days ago4.Half an hour__________(pass)since the train ________(leave)5.Mary __ 3(7-x)=5x-43 因式分解:x-xy^2=_____,169x^2y^2-1=____.ab^3-a^3b=____,(x-y)^2-1=_____.x^3-16x^2+64x=______,2x^2-4x+2y^2=______.25(x-y)^2-10(x-y)+1=______ 个人优势怎么写 根据x^4+4 =x^4+4x^2+4-4x^2 =(x^2+2)^2-4x^2 =(x^2+2+2x)(x^2+2-2x) 用上述方法将x^4+x^2y^2+y^4因式分解 自己的优势 (怎么写具体啊?) 个人优点怎么写 阴阳平衡(翻译英语)
