Limsin(xn)\/(sinx)m
原式=limx^n\/x^m(分子,分母同时用等价无穷小代换) =limx^(n-m) = 0 n>m 1 n=m 无穷大 n。
limx趋近于0sin(xn)\/(sinx)m
lim<x→0> sin(x^n)\/(sinx)^m = lim<x→0> x^n\/x^m 当 n>m , 该极限为 0;当 n=m , 该极限为 1;当 n<m , 该极限为 ∞.
lim sin(x的n次方)\/sinx的 m次方,用等价无穷小求极限
回答:解:当x→0时,sinx??n~x??n,(sinx)??m~x??m;∴limsin(x??n)\/(sinx)??m=limx??n\/x??m=limx??(n-m)=0.

=lim(x->0) x^n\/x^m =lim(x->0) x^(n-m)case 1: m<n , lim(x->0) sin(x^n)\/(sinx)^m=lim(x->0) x^(n-m) =0 case 2: m=n , lim(x->0) sin(x^n)\/(sinx)^m=lim(x->0) x^(n-m) =1 case 3: m>n , lim(x->0) sin(x^n)\/(sinx)^m=lim(x...
求极限lim(x趋于0时)sin(sinx)\/x
当x趋近于0时,sinx=x 所以原式=sinx\/x=1
limsinx(n次方)\/(sinx)m次方
用等价无穷小,x->0时,sin(x^n)->x^n,(sinx)^m->x^m 所以 limsinx(n次方)\/(sinx)m次方 =lim x^n\/x^m =x^(n-m)若n>m,原极限=0 若n=m,原极限=1 若n<m,原极限=∞
