A={(x,y)|x=2},B={(x,y)|y=3},求A∩B和AUBA={(x,y)|x=2},B={(x,y)|y=3},求A∩B和AUBA={(x,y)|x=2},B={(x,y)|y=3},
A={(x,y)|x=2},B={(x,y)|y=3},求A∩B和AUB
A={(x,y)|x=2},B={(x,y)|y=3},求A∩B和AUB
A={(x,y)|x=2},B={(x,y)|y=3},求A∩B和AUB
A∩B={(2,3)}
A∪B={(2,y),(x,3),x∈R,y∈R,y≠3}
是这样么?
y=a^x*b^x求导
若集合A={(x,y)|y>=|x-2|} ,B={(x,y)|y
A={（x,y)|y>=0.5|x-2|},B={(x,y)|y
A={(X,Y)|X+Y>=1},B={(X,y)|X^2+y^2=1},B={(X,y)|X^2+y^2
集合A={y/y=1-x-4/x},B={X/X^2-(3+a)X+3a
集合A={y|y=1-x-(4/x)},B={x|x^2-(3+a)x+3a
抛物线y=2-(x-a)(x-b)(a
[a'(x)b(x)-a(x)b'(x)]/b(x)^2//如何通分得到的?y(x)=a(x)/b(x)分子求导a'x/b(x),对分母求导是-a(x)b'x/b(x)^2两者通分相加[a'(x)b(x)-a(x)b'(x)]/b(x)^2
x分之a十x分之b=?x-y分之x^2十y-x分之y^=?
A={(x,y)|y=x^2,x∈R},B={(x,y)|y=x,x∈R},求A∩B
假设集合U={(x,y)|x∈R,y∈R },A={(x,y)|2x-y+m>0},B={(x,y)|x+y-n
已知x+y=a,x-y=b.求:x^2+y^2;xy
x+y=a,x-y=b.求2x-3y等于
4a(x-y)二次方-2b(y-x)二次方+(y-x)=
A={(x,y)|y=-x^2+mx-1},B={(x,y)|y=3-x,0A={(x,y)|y=-x^2+mx-1},B={(x,y)|y=3-x,0
初一因式分解练习题,谁好心帮我解下表示平方1.2X~-3XY-X2.(X+Y)~(X+Y)(X-Y)(X+Y)(Y+Z)3.3X(a+2b)~-6XY(a+2b)4.a(x-y)-b(X-Y)-C(Y-X)5.(b-a)~-2a+2b6.(x-y)~-m(y-x)+y-x7.x(x-y)(a-b)-y(y-x)(b-a)8.已知a+b=13,ab=40,求 b+ab~的值
已知x属于R,y>0,集合A={x|x*x+x+1,-x,-x-1},集合B={-y,-y/2,y+1}若A=B,则x*x+y*y的值为
A:{(x,y)|y=x方+2x},B:{(x,y)|y=x+a},A交B的真子集为空集,求a的范围
