你写的式子不规范:
如果是lim{x^2*y^2/[x^2*y^2+(x-y)^2]}的话,(x,y)趋近于(0,0)时极限不存在
令y=k*x,即y与x为线性关系
原式化为lim{x^2*(k*x)^2/[x^2*(k*x)^2+(x-k*x)^2]}=lim{1/[1+(1-k)^2/x^2]}
lim sin(y×x^2+y^4)/(x^2+y^2) x,y都趋于0,
x.y都趋于正无穷大时:lim(x^2+y^2)e^-(x+y)?
lim(x→∞,y→∞) x+y/x^2-xy+y^2
极限x,y趋向0 lim x y/(x^2+y^2) =( ).
求极限lim(x→+∞,y→+∞) (X+Y)/(X^2-Y^2)
lim(x→∞,y→∞) x+y/x^2-xy+y^2
lim((x^2)y)/(x^4+y^2),x和y都趋向于0
lim(x+y)cos(1/(x^2+y^2))且x,y趋于0
lim(x→0y→1)(1+xe^y)^(2y+x/x)求极限
证明 lim(2x-y)/(x+y) 不存在(x,y)趋于(0,0)
lim(x,y)趋向于(无穷,a) (1+1/x)^(x^2/(x+y))answer:e
lim(x→+∞,y→0) (1+1/x)^(x^2/(x+y))
lim(x,y)->(∞,a)(1-1/x)^(x^2/x+y)
lim(x,y)->(0,2)(1-3xy)^2/x
1.lim(2x-sinx)/(2x+sinx) (x→0)2.lim(sinsinx)/x (x→0)3.lim 4/y (y→∞)
(lim) x/(x-y)
lim(xy/(x^2+y^2))^x^2 x,y趋近无穷 求极限
求极限lim(x,y)→(+∞,+∞) (xy/(x^2+y^2))^x^2
