lim(n趋向于∞)[1/(n^2+1)+3/(n^2+1)+…+2000/(n^2+1)]主要的是过程,答案是次要的

lim (1+1/2n)^n n趋向于无穷大 lim√1+1/n^2 n趋向于无穷大 lim(n/(n^2+1)+...+n/(n^2+n))x趋向于无穷 求解答过程~ lim x趋向于∞(2n-1/3+根号n平方+1)的极限 求极限:Lim(1+1/n-1/n^2)^n n趋向于正无穷 lim x趋向于无穷 (2^n+1+3^n+1)/(2^n+3^n)= 求lim趋向于无穷3^n+(-2)^n/3^(n+1)+(-2)^(n+1) 求极限 n趋向于无穷 lim（(根号下n^2+1)/(n+1)）^n 求极限lim(n趋向于无穷）(n+1)(根号下(n^2+1)-n) n趋向于无穷大,lim n[ln(n+2)-ln(n+1)], lim(2^n+3^n)^1 (n趋向无穷) 判断极限是否存在lim [n+(-1)^n]/n n趋向于无穷 lim |x|/x x趋向于0 n趋向于无穷 lim[1-1/(2n+1)]^n 怎样算 lim(n趋向于无限大)1+2^2+2^4+...+2^2n/4^n 证明lim(n/(n^2+1))=0(n趋向于无穷大） lim(100sin(n!))/(2n-1)n趋向于+无穷.大一高数题. lim(n^2(cos1/n-1))(n趋向于无穷大） 求极限lim n趋向于无穷（1/n）*√(n+1)(n+2)⋯(n+n)
