解答
因为lim x→0 [sin6x/(6x)]=1
所以,
lim x→0 [sin6x+xf(x)]/x^3
=lim x→0 [6x+xf(x)]/x^3
=lim x→0 [6+f(x)]/x^2
=0
推荐
- 若lim [sin6x+xf(x)]/x^3=0,则lim [6+f(x)]/x^2是多少?（x是趋近0）
- 已知lim x→0 [sin6x+xf(x)]/x^3=0,求 lim x→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=?
- 假设lim(x趋于0)[(sin6x+xf(x))/x^3]=0,则lim(x趋于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=?
