<p>
Dit is een wiskundige formule, meer bepaald uit de <a href="http://nl.wikipedia.org/wiki/Goniometrie" class="urlextern" title="http://nl.wikipedia.org/wiki/Goniometrie"  rel="nofollow">Goniometrie</a><br/>
</p>
<p>
De functie berekent de sinus van <em>uitdrukking</em>.  De hoek moet in radianen worden meegegeven (0 tot 2pi).<br/>
