lim(n趋向于无穷)(1-e^（1/n）)sinn

lim n趋向于无穷 n[(（n+1）/n)^n-e] lim(n趋向于无穷)(1-e^（1/n）)sinn lim n[e2-(1+1/n)^2n],当n趋向于无穷答案等于e^2 lim n趋向于无穷(1+e^n+派^n)^1/n,已经知道是用夹逼准则,请问怎么用 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 求lim n趋向于无穷 n(n^1/n -1)/ln n lim根号n*n+n除以n+1=?（档n趋向于无穷） lim(n/(n^2+1)+...+n/(n^2+n))x趋向于无穷 求解答过程~ lim n((1+n)的n次-e) 等于多少 n趋向无穷 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 求极限 n趋向于无穷 lim（(根号下n^2+1)/(n+1)）^n lim x趋向于无穷 (2^n+1+3^n+1)/(2^n+3^n)= 求极限lim(n趋向于无穷）(n+1)(根号下(n^2+1)-n) 求lim趋向于无穷3^n+(-2)^n/3^(n+1)+(-2)^(n+1) n趋向于无穷 lim[1-1/(2n+1)]^n 怎样算 lim(n趋向于无穷）[（-1）^n+1]/n lim(n趋向于正无穷)(x^n-1)/(x^n+1)=?,
