Homework Help: Limit Problem

Try writing x²+1 as x²(1+1/x²).

See if that helps.

 

And remember that [itex](1/x)\sqrt{x^2+ 1}= \sqrt{(1/x^2)(x^2+ 1}[/itex]

 

put your x in to the square root by making it X^2....then it will be easy because you will get something like
limit x--->infinity sqrt(1+1/X^2)
and when x goes to infinity 1/X^2 goes to zero
so your final limit will go to 1
hope you got it!!!!!!!!!!!!
