lim(1+1/n+1/n^2)^n,n趋近无穷lim(1+1/n+1/n^2)^n,n趋近无穷lim(1+1/n+1/n^2)^n,n趋近无穷原式=lim(n->∞){[1+(n+1)/n²
lim(1+1/n+1/n^2)^n,n趋近无穷
lim(1+1/n+1/n^2)^n,n趋近无穷
lim(1+1/n+1/n^2)^n,n趋近无穷
原式=lim(n->∞){[1+(n+1)/n²]^[(n²/(n+1))((n+1)/n)]}
=【lim(n->∞){[1+(n+1)/n²]^[n²/(n+1)]】^{lim(n->∞)[(n+1)/n]} (应用初等函数的连续性)
=e^{lim(n->∞)[(n+1)/n]} (应用重要极限lim(z->0)[(1+z)^(1/z)]=e)
=e^[lim(n->∞)(1+1/n)]
=e^(1+0)
=e.
