x趋近0时，lim（6x-sin6x）/x的3次方=？

x趋近0时，lim（6x-sin6x）/x的3次方=？ lim(x趋近于0)[sin6x+xf(x)]/x^3=0,则lim(x趋近于0)[6+f(x)]/x^2=? 求极限lim(x->0)(sin6x-6x)/x^3, 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=? 设x->0时,lim((sin6x+xf(x))/x^3)=0,求x->0时,lim((6+f(x))/x^2). lim（x趋于0）（sin6x-xf(x)）/x^3=0,求lim（x趋于哦0）（6-xf(x)）/x^2. x趋于0,lim x-o ( sin6x+xf(x))/x3=0 ,lim x-o (6+f(x))/x2=? 假设lim(x趋于0)[(sin6x+xf(x))/x^3]=0,则lim(x趋于0)[(6+f(x))/x^2]=?, 已知lim x→0 [sin6x+xf(x)]/x^3=0,求 lim x→0 [6+f(x)]/x^2? lim x→0 [sin6x+xf(x)]/x^3=0,求 lim x→0 [6+f(x)]/x^2 求极限当x→0若lim[sin6x+x f(x)]/x^3=0,求lim[6+ f(x)]/x^2
