G prove that limx→∞(x 2 + 1)/x2 = 1 using the definition of limit at ∞.
Maslowich
\displaystyle\lim_{x\to\infty}\frac{x^2+1}{x^2}=1

means to say there is some number M for which any choice of \varepsilon>0 such that

x>M\implies\left|\dfrac{x^2+1}{x^2}-1\right|

Working backwards, we have

\left|\dfrac{x^2+1}{x^2}-1\right|=\left|1+\dfrac1{x^2}-1\right|=\dfrac1{x^2}
\implies\sqrt{\dfrac1{x^2}}

So, whenever x>M=\dfrac1{\sqrt\varepsilon}, we can always guarantee that \left|\dfrac{x^2+1}{x^2}-1\right|.
