已知lim(n2+1/n+1-an-b)=1求a,b 对了 那是n的平方 n趋近正无穷
已知lim(n2+1/n+1-an-b)=1求a,b 对了 那是n的平方 n趋近正无穷
lim(n到无穷) n2/n+1+an+b=0.a=?b=?
lim(n2+2n+2)/(n+1)-an)=b,求a,b
求极限lim((n+1)/(n2+1)+(n+2)/(n2+2)+...+(n+n)/(n2+n)),n趋近无穷
已知lim(n的平方+1/n+1+an-b)=1,求a,b的值
1.求lim[1/(n2+n+1)+2/(n2+n+2)+.+n/(n2+n+n)][n趋于无穷][n2为n的平方]
已知:lim (n→∞) [(n^2+n)/(n+1)-an-b]=1 ,求a,b的值
a,b为常数.lim(n->无穷)an^2+bn+2/2n-1=3 求a,b
lim(n2+1/n+1-an-b)=0,求a,b
设f(x)在x=a处可导,f(a)>0,求N趋近于正无穷时lim{f(a+1/n)/f(a)}的N次方.
已知lim[(an^2+5n-2)/(3n+1)-n]=b,求a,b的值
