lim(1-1/2^n)=1 n趋向于无穷大

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 x趋向于无穷 (2^n+1+3^n+1)/(2^n+3^n)= 证明lim(n/(n^2+1))=0(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根号n*n+n除以n+1=?（档n趋向于无穷） lim(2^n+3^n)^1 (n趋向无穷) 求极限:Lim(1+1/n-1/n^2)^n n趋向于正无穷 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)], 证明 lim(1-1/2^n)=1 n趋向于无穷大 lim(1-1/2^n)=1 n趋向于无穷大 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 用ε-Ν定义证明lim(1-n)/(1+n)=-1,n趋向于无穷大 n趋向于无穷 lim[1-1/(2n+1)]^n 怎样算 lim(n趋向于正无穷)(x^n-1)/(x^n+1)=?,
