+
+<p>El mètode <code>Math.sin()</code> retorna un valor numèric entre -1 i 1, que representa el sinus de l'angle donat en radiants.</p>
+
+<p>Degut a que <code>sin()</code> és un mètode estàtic de <code>Math</code>, sempre s'utilitza com a <code>Math.sin()</code>, en comptes de com a mètode d'una instància de <code>Math</code> (<code>Math</code> no és un constructor).</p>
