Homework Statement
Determine the limit and then prove your claim.
limx[tex]\rightarrow[/tex][tex]\infty[/tex] (1+[tex]\frac{1}{x^2} }[/tex]) x
Homework Equations
I know that the formal definition that I need to use to prove the limit is:
{limx[tex]\rightarrow[/tex][tex]\infty[/tex] (1+[tex]\frac{1}{x^2}[/tex])x=1}={[tex]\forall[/tex] [tex]\epsilon[/tex]>0, [tex]\exists[/tex] N > 0, [tex]\ni[/tex] x>N [tex]\Rightarrow[/tex] |f(x)-1|< [tex]\epsilon[/tex]}
The Attempt at a Solution
We have to use Taylor Expansions to find the Taylor polynomial of f(x) and bound the errors to solve for [tex]\delta[/tex], given [tex]\epsilon[/tex] >0.
The "x" exponent, however, is throwing me off. Could someone help guide me through the Taylor expansion of f(x)? I'd greatly appreciate it!
