Homework Statement
prove that ##\lim_{x \to \infty} \frac{\sqrt{x+1}}{x} = 0## where ##x>0##
Homework Equations
Definition: Let ##A\subseteq\mathbb{R}## and let ##f:A\rightarrow \mathbb{R}##. Suppose that ##(a,\infty)\subseteq A## for some ##a\in\mathbb{R}##. We say that ##L\in\mathbb{R}## is the limit of ##f## as ##x\rightarrow\infty## and write ##\lim_{x \to \infty} f=L## if any given ##\epsilon>0## there exists a ##K=K(\epsilon)>a## such that for any ##x>K## then ##|f(x)-L|<\epsilon##.
The Attempt at a Solution
I can't seem to connect this definition to the problem because the part that is confusing is connecting ##a## to ##\epsilon##. What I have so far is Suppose that ##(1,\infty)\subseteq A## where ##a=1##. Let ##\epsilon >0## then there exists a ##K\in\mathbb{N}## such that if ##x>K## then... Let's just say I am completely stuck.
