lim(√(n2+2n)-n) 当n趋向无穷时

lim(√(n2+2n)-n) 当n趋向无穷时 求 证Lim ( n/ n2+1) + (n/ n2+2) +( n/ n2+3).+(n/n2+n)当n趋向无穷时的极限为1 极限lim n2^n/n^n= n趋向于无穷大极限lim n2^n/n^n=？ 求lim【1/(n2+π)+1/(n2+2π)+...+1/(n2+nπ)】(n趋向于正无穷) lim[n/(n*n+1*1)+n/(n*n+2*2)+...+n/(n*n+n*n)],当x趋向无穷大时,怎么求极限, lim(2^n+3^n)^1 (n趋向无穷) lim√1+1/n^2 n趋向于无穷大 求当n趋向无限大时lim[(n+1)^2/(n-1)]的极限? 当n趋向于正无穷,求lim{{(根号（4n^2+n）)+n}/(n+2)} lim[(-2)^n+3^n]/[(-2)^(n+1)+3^(n+1)] 当n趋向于无穷时 lim( sinnπ/n) ,当n趋向无穷时 lim (1+1/2n)^n n趋向于无穷大 请数学能手来看看这题lim{（1/N2+1)+(2/n2+2)+.+(n/n2+n)}n2是n的平方,n趋向无穷是求极限。。不是求N。。。。。N是不小心打成大写 求极限lim n趋向于无穷（1/n）*√(n+1)(n+2)⋯(n+n) 求极限lim(n/(n2+1)+n/(n2+2^2)+……+n/(n2+n2)) 极限运算：lim{[2^(2n+1)-8]/[4^(n+1)+3^n]}当n趋向正无穷, lim n[e2-(1+1/n)^2n],当n趋向于无穷答案等于e^2 求极限lim((n+1)/(n2+1)+(n+2)/(n2+2)+...+(n+n)/(n2+n)),n趋近无穷
