请问:f(x)=2-(x分之3)limx*sin(1/x)
limx趋于0x/f(3x)=2,求limx趋于0f(2x)/x
lim1/根号n*sin (n趋近于无穷),limx^3+1/4-x^2(x趋近于2),limx^2+1/x-1/x^2
limx趋近于0 x/f(3x)=2,limx趋近于0 f(2x)/x=
已知{limx趋近0 [(sin6x)+xf(x)]/x^3}=0 求limx趋近0 [6+f(x)]/x^2=?答案是
已知limx趋近0 [6+f(x)]/x^2=36,求limx趋近0 [(sin6x)+xf(x)]/x^3=?
若limx→0 f(2x)/x=2,则limx→无穷x*f(1/2x)等于?
求这道题的错误原因limx^3(sin1/x-1/2siin2/x)=limx^3sin1/x-lim1/2x^3sin
已知函数f(x)=2倍根号3sin(x-4分之π)cos(x-4分之π)-sin(2x-π) (1)求函数f(x)的单调
判断奇偶性f(x)=根号2sin(2x+2分之3π)
(1) limx趋于-∞根号下3x^2+1/x=?(2) limx趋于∞(2x+1/2x+3)^x=?
limx趋于无穷(x/x-1)^3x-1
若limx→2 f(x)-5/x-2=3,求limx→2 f(x)极限值
