lim(n到无穷) n2/n+1+an+b=0.a=?b=?
lim(n2+1/n+1-an-b)=0,求a,bn2+1/n+1:n方加1除以n+1
An=(-2-1/n2,1/n) lim n→∞ An=
lim(n2+2n+2)/(n+1)-an)=b,求a,bn2是n平方lim((n平方+2n+2)/(n+1)-an)=b
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
求极限lim(n/(n2+1)+n/(n2+2^2)+……+n/(n2+n2))
已知lim(a根号下(n2+2n)-bn)=1,求实数a+b
计算lim(1/n2+1+2/n2+1+3/n2+1+...+n/n2+1)
如何证明lim(n~正无穷)1/n2=0
lim(7-1/n)=?是不是可以把7和1/n单独分开看,就是lim(an)=7,lim(bn)=lim(1/n)=0,lim(an-bn) =lim(7-1/n)=7,或者lim(bn)=lim(-1/n)=0,那么lim(an+bn)=lim(7+(-1/n))=lim(7-1/n)=7所以lim(7-1/n)
lim[(n平方+1)/(n+1)-an-b]=1,求实数a、b具体~
大一求极限lim(n/(n2+1)+n/(n2+2^2)+……+n/(n2+n2))pi/4
lim(an^2/(3n+1)-n)=b a+b=?
求极限lim((n+1)/(n2+1)+(n+2)/(n2+2)+...+(n+n)/(n2+n)),n趋近无穷
设{an},{bn},{cn}均为非负数列,且lim(n->无穷)an=0,lim(n->无穷)bn=1lim(n->无穷)
lim[(n^2+1)/(n+1)-an-b]=o求a和b的值 lim[1/(a-1)^n]=0 求a的范围lim[(n^2+1)/(n+1)-an-b]=o求a和b的值 lim[1/(a-1)^n]=0 求a的范围
lim n趋于无穷 ,an+1/an=q.求lim an=?
lim(an+1-an)=d,求证lim(an/n)=d
