LIM[ln(1+n)/n] n趋于无穷 怎么算怎么算的呀帮个忙

lim n趋于无穷时：[ln(n+2)/(n+2)]*[(n+1)/(ln(n+1)]? 当该极限n趋于无穷是 lim (ln(1+n)) / (1+n) LIM[ln(1+n)/n] n趋于无穷 怎么算怎么算的呀帮个忙 lim( n/n+1)^(n+2) 趋于无穷 ln(2n^2-n+1)-2ln n.当n趋于正无穷是的极限 lim (1+2/n)^2=?n趋于无穷lim (1+2/n)^2=?n趋于无穷 lim(n趋于无穷)[Σ(k从1到n)ln(1+k/n)/(n+k/n)]答案是2ln2-1,求过程 lim(1/n^3+(1+2)/n^3+...+(1+2+...+n)/n^3)n趋于无穷 lim 2n^2+n+1/n^2-2n+1n趋于无穷 lim(n趋于无穷)[n(n+1)/2]/n方+3n的极限是多少? 当n趋于无穷时limn【ln(1+n)-ln(n-1)】的极限 求ln(1+2^n)*ln(1+3/n)的极限(n趋于无穷) 求lim n趋向于无穷 n(n^1/n -1)/ln n 求lim[(2n-1）/（2n+1)]^n,n趋于无穷 求极限：lim((2n∧2-3n+1)/n+1)×sin n趋于无穷 极限题：lim[n*tan(1/n)]^(n^2) (n趋于无穷） lim（n^3＋3^n）^1/n n趋于无穷 高数 lim n趋向无穷 lim（3^(1/n)-1)ln(2+2^n)
