Question

solved question of limit

Answer 1

Hi !!!!

Put x = infinity we get. infinity / infinity

So, by Applying L-hospitals rule ( differentiation nr and dn separately till u come out from infinity/infinity.)


Lt. (9x² +2x )/ (2x -1 )
x->inf.

Lt (18x +2 ) / 2
x->inf

now put x = inf.

we get. infinity.


2nd Method :-

x ³ { 3 + (1 / x ) - (1/ x³)}. /. x ² { 1 -( 1 / x ) + (7 / x²)}

put x = inf.

we get

infinity
