lim((sin(x^n))/((sinx)^m)),x→0,求极限高数第六版,习题1-7,第4题（2）,怎么求出n/m来

lim(x(sin)^2) lim(x趋向无穷)(sin n)/n=? lim(n→1)sin(1-x)/(x^3-1) lim arc tan(x-sin(lnx)) n趋于无限大 求极限 x→π lim sin mx/sin nx (m,n∈N) 求lim(x->&无穷)sinn/n,求lim(x->无穷)sin(1/n) 求lim(cos^n次方x-sin^n次方x)/(cos^n次方x+sin^n次方x) 求lim(n趋近于正无穷)（sin根号（x+1）-sin根号(x)） 极限 lim(x-->无穷)(1/n sin(n)+1/n sin(1/n)+nsin(1/n))求极限lim(x-->无穷)(1/n sin(n)+1/n sin(1/n)+nsin(1/n)) 用等价无穷小量代换求极限 lim (x趋于0) sin x^n/(sin x)^m (m,n为正整数)lim (x趋于0) sin x^n/(sin x)^m (m,n为正整数) lim x->无穷大 （n-sin n）/(n+cos n)=? 求lim((sin²x-sin²9)/(x-9)),x→9 lim((x+n)/(x-n))的x次方,x→∞ lim x->0 (sin x-tan x)/sin (x^3) Lim(n→∞) 2的n次方sin x/2的n次等于多少? lim 2^n *sin(x/2^n)n→∞求极限 lim(n→∞){2^n[sin(x/2^n)]}求详细过程,谢谢! lim n*sin(x/n)如题,n趋近于无穷大,这个极限咋么求.. 请问怎样求极限lim(x→无穷)n·sin(x/n)?
