The main purpose of this post is to test if my configuration works well. So, let&rsquo;s test: </p> \[ \begin{align*} f: \mathbb{R} &\to \mathbb{R}\\ x &\mapsto x^2 \end{align*} \]<p> Nice, isn&rsquo;t it?</p> <p>Let \(g: A \subset E \to F\), where \((E,\ ||\cdot||_E)\) and \((F,\ ||\cdot||_F)\) are normed vector spaces, and let \(a \in \bar A\) and \(\ell \in F\). We define: </p> \[ g(x) \xrightarrow[x \to a]{} \ell \enspace\overset{\text{def}}\iff\enspace \forall \varepsilon>0, \exists \eta>0, \forall x \in A, 0<||x-a||_E < \eta \implies ||g(x)-\ell||_F<\varepsilon \]<p> Great.</p>
