lim(n->无穷)(1/4n^2-2^2+2/4n^2-3^2+...+n-1/4n^2-n^2) 用定积分求

lim(2^n+3^n)^1 (n趋向无穷) 1、lim n->无穷 根号[(n^4+n+1)-n^2]*(3n+4) lim(1+1/(n+2))^n其中n趋近无穷 lim( n/n+1)^(n+2) 趋于无穷 求lim(n->无穷)(3n+5)/(n^2+n+4)^1/2的极限 lim(n趋近于无穷)(1+2+3+.+n)/(3n^2+4n)等于多少 求解lim((3^1/n+4^1/n)/2)^n n趋向正无穷. 求极限,lim(1+n)(1+n^2)(1+n^4)-----(1+n^2n)=?（n趋于无穷） lim{[n*(n+1)*……*(2n-1)]^1/n}/n n->无穷答案是4/e 求两道极限题的解 lim(n->无穷）1+2+3+.+(n-1)/n^2lim(n->无穷)1+1/2+1/4+.+1/2^n Lim(1-3/2n)^4n+5.n趋于无穷,求极限 lim(n->无穷) （tan(pi/4 + 1/n)） ^n的极限 为什么是 e^2 lim (1+2/n)^2=?n趋于无穷lim (1+2/n)^2=?n趋于无穷 高数 lim n趋向无穷 lim（3^(1/n)-1)ln(2+2^n) 为什么lim n趋向无穷 (5n^2-4n)/(3n^2+2n-1)等于5/3 lim 2n^2+n+1/n^2-2n+1n趋于无穷 lim n趋近无穷 3n^3+n^2-3/4n^3+2n+1的极限 lim(n+2)(n-1)/3n^2+2n+1= n趋近于无穷
