lim_(x rarr oo){(1)/(1-x^(2))+(2)/(1-n^(2))+(x)/(1+0)+(n)/(1-n^(2))}=

lim_(x rarr oo){(1)/(1-n^(2))+(2)/(1-n^(2))+(n)/(1-n^(2))} is equal to 0 (b) -(1)/(2)(c)(1)/(2)(d) none of these

lim_(n rarr oo) ((1)/(1-n^(2)) + (2)/(1-n^(2)) +…...+(n)/(1-n^(2))) is :

lim_(x rarr oo) (1+2/n)^(2n)=

lim_(x rarr oo)(n+1)/(2n^(2)+n-1)

Evaluate :(lim_(x rarr oo))_(x rarr oo)(1)/(1+n^(2))+(1)/(2+n^(2))+...+(n)/(n+n^(2))

lim_ (n rarr oo) [(1) / (1-n ^ (2)) + (2) / (1-n ^ (2)) + ... + (n) / (1-n ^ (2 ))] is

lim_(x rarr oo) ((2n+1)(3n+2))/(n(n+9))=
