Molt bé. Les imatges seran el resultat d'aplicar el sinus a un nombre, per tant, el recorregut coincideix amb el de la funció sinus.

Atenció, les imatges són el resultat d'aplicar el sinus a un nombre, per tant, el recorregut coincideix amb el de la funció sinus. No s'estan multiplicant les imatges de la funció sinus per #a.
Choice 3

Atenció, en multiplicar l'angle per #a abans d'aplicar el sinus, estem modificant el període. <br />
