当x趋于0 lim sin3x/tan7x的极限是多少
极限Lim(x->0)(sin3x)/x=
lim(x->0) tan2x/sin3x
极限 lim(x->0) ln(tan7x)/ln(tan2x)
lim(x→0)ln tan7x/ln tan2x= lim(x->0) [7(tan2x)·cos²2x]/
lim X趋向于0 arcsin2x/sin3x
lim(x趋向于0)arctan2x/sin3x
当x趋于0+时,lim (ln tan7x)/(ln tan2x)怎么求,
lim(sin3x/x^3+a/x^2)=b (x趋于0) 求a,b
求极限 lim x趋近于0 sin3x/7x
求lim(x→0)x/sin3x的极限
求极限lim(x→0)sin3x/x
