		<summary type="html">&lt;p&gt;inicial&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Página nova&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Ferramenta matemática que possui um enunciado rigoroso, mas cujo real uso é para demonstrar o melhor caminho para chegar ao bandeco.&lt;br /&gt;
&lt;br /&gt;
==Enunciado==&lt;br /&gt;
Seja &amp;lt;math&amp;gt;f: [a,b] \to \R&amp;lt;/math&amp;gt; uma função contínua e suponha que &amp;lt;math&amp;gt;f(a)f(b)=-1&amp;lt;/math&amp;gt;. Então, existe pelo menos um &amp;lt;math&amp;gt;c&amp;lt;/math&amp;gt; no intervalo aberto &amp;lt;math&amp;gt;(a,b)&amp;lt;/math&amp;gt; tal que &amp;lt;math&amp;gt;f(c)=0&amp;lt;/math&amp;gt;.&lt;br /&gt;
==Demonstração==&lt;br /&gt;
Veja [[Teorema do Valor Intermediário]].&lt;/div&gt;</summary>
