若极限lim(x-0)[sin6x+xf(x)]/x^3=0,则lim(x-0)[6+f(x)]/x^2=?

lim(x趋近于0)[sin6x+xf(x)]/x^3=0,则lim(x趋近于0)[6+f(x)]/x^2=? 假设lim(x趋于0)[(sin6x+xf(x))/x^3]=0,则lim(x趋于0)[(6+f(x))/x^2]=?, x趋于0,lim x-o ( sin6x+xf(x))/x3=0 ,lim x-o (6+f(x))/x2=? 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 设x->0时,lim((sin6x+xf(x))/x^3)=0,求x->0时,lim((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 求极限lim(x->0)(sin6x-6x)/x^3, lim（x趋于0）（sin6x-xf(x)）/x^3=0,求lim（x趋于哦0）（6-xf(x)）/x^2. 求极限当x→0若lim[sin6x+x f(x)]/x3=0,求lim[6+ f(x)]/x2 求极限当x→0若lim[sin6x+xnbsp;f(x)]/x3=0,求lim[6+nbsp;f(x)]/x2 求解一道极限运算题lim{sin2x+xf(x)}/x^3=1 (x→0） lim{2cosx+f(x)}/x^2这类题
