求极限 lim n*sin(x/n) （n趋于无穷大）,答案给的好像是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)) 求极限 x→π lim sin mx/sin nx (m,n∈N) lim 2^n *sin(x/2^n)n→∞求极限 请问怎样求极限lim(x→无穷)n·sin(x/n)? 求极限：lim(sinx/(2^n*sin(x/2^n)))要详细过程, 求极限 lim x-无穷 sin(n+1)/(n+a) 正无穷 求极限Lim（(n-x)/(n+2))^(n+1) 求极限lim(1/n)*[(sin(pi/n)+sin(2pi/n)+.+sin(n*pi/n)] n->无穷 求极限 lim n*sin(x/n) （n趋于无穷大）,答案给的好像是x. 求下列极限.lim(n趋向于无穷大)(2x次方)*(sin*1/2x次方) lim n趋于无穷2的n次方sin(x/2的n次方)的极限怎么求 利用无穷小的性质求极限lim(x→+∞)[(n^2+1)/n^3]sin(n!)= 求极限 lim sin pi(n^2+1)^(1/2) 求极限 lim sin pi*(n^2+1)^(1/2) 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) 求极限：lim((2n∧2-3n+1)/n+1)×sin n趋于无穷 求极限lim n→∞ 根号n乘以sin n 除以n+1 lim(x→0）sin(x的n次方）/（sinx）的n次方求极限
